Do you all have Mr. Number on you cell phone by chance? I did. and I started getting these spam calls all the time...repeatedly by the hour and minute some time. I would then call my carrier and have the number blocked the calls would begin in a matter of weeks again. Anyway I removed Mr. Number and yes the spam numbers started immediately! How I figured this out was when you're a repeat for this service they call you with a verification code and that area code exposed the whole thing! Check your phone.

Document phone calls after sending certified letter of cease and desist communication. . Keep FTC complaint number. Each call they make to you after these measures will cost them big bucks. keep your call log documented.

This company keeps calling my home and cell phones from this and similar numbers (856-295-9741 e.g.) and I keep saying to take me off the list; they still call. Somebody shut these people down please!

Scam! Hang up! Don't press any numbers when they call you!

A recording said "you've won a vacation from *** Security Co." Then they put me on hold. When I told them to take my number off their list, they said "I took your number" and then hung up. This is illegal. They are supposed to take you off their list when you ask. Not hang up on you half way through your request. I hope these scoundrels get into big trouble. I am very protective of my cell number. I do not have time to deal with solicitors.

Man these WCA people call me like crazy they call me like everyday with different numbers and expect me to pick up.. I already cussed them out!

Phony debt collectors with Indian accents are calling people trying to scare them into paying debts that are not theirs. Some of the company names they use are American Credit Services, TAC Evolution, Allied Financial Services, CashNetUSA, Sonic Bank, Sonic CashNet, CashLand, and Cash America. If you know of others, please add them in the comments section below. The fake debt collectors call and say you will be arrested and thrown in jail unless you send money immediately. The amounts claimed seem to be $400 or $1,095 and a smattering in between. The calls most often arrive on a Friday when all government office are closed so you can?t check out their story. The callers use the names of real attorneys they found on the internet. The goal of the scam is to scare the person getting the call into sending money via Western Union or MoneyGram or to give up their bank details to hit your bank account, in order to prevent the police from coming to arrest you in the next few hours. If you want to listen t what these calls sound like, click here. Apparently there are a number of telephone numbers tied to this scammer that I believe is calling from a call center in India via voice over IP, (VOIP). So the callers really are not even in the United States although they pretend to be. Armed with the contact information the scammers in India call make outbound calls on a VOIP telephone line and forge any outgoing phone ID they want. It?s not hard to do. (By the way, if you want to unmask any blocked number and find out who is calling, try Trapcall.) They might even use a number from a block of VOIP numbers they?ve rented to receive return calls. After a short period of time they dump the number and start using a new number. I found at least one of the numbers listed as being used by these scammers was issued by LES.net, a VOIP service provider.

I'm only 17 and this number keeps calling me while im in class everyday along with some other ones

Just dont answer their calls and they leave you alone. Not saying that what they're doing is right, but if enough people ignored them they would have to quit.

It is interesting how those people always call when I am away from the phone, and they NEVER leave a message. Doing an internet search I learned that this is part of a network of hucksters that are out to collect information from people, when they actually answer the telephone. Once they "harvest" information from people, they will use it for fraud or other nefarious purposes. Caution! Don't answer, and if you do, hang up immediately! Those phonies need to get a life!

856-295-5677 This number is calling me every single day...They are trying to find out personal info...

So Be careful they seem to be Crooks....!!!

Called cell. I don't answer unless i know who it is.
Also getting calls from 850,312,805,509,612, 530. Apparently they have phones all over.

THESE PEOPLE CONTINUE TO PESTER ME ALL THE TIME I'S DRIVING ME NUTS

Just received a call from this number at 7:45 pm EST.  I didn't answer and no message was left.  Maybe I'll harass HIM/HER next time if I answer it!!

called my cell 2h ago

Since the "Do Not Call" list doesn't seem to work and pressing 3 to opt out means nothing to these people, I have some fun at their expense. I Keep a recorder next to my phone and wait for a live person to ask me my name and blow until they hang up. I get my four children to make as much noise as they possibly can using very loud musical instruments, pots and pans, etc., and whenever we need to rest, I turn up the speakers with some ridiculous song from YouTube. This technique has dramatically reduced the number of calls I get.

something about a visa card

The "WCA" keeps calling me.  I don't know who they are or what they want I just want them to stop.

This number called my cell for the first time, just now. I didn't pick it as usual, since it's an unrecognized number. I was sure it's not worth my effort and 10 cents (my cell is a prepaid type).

same here, they keep calling me. i cussed this guy out already!

Got a call from them just now. When I answered it, an automated message started playing so I hung up immediately. Very annoying.

They have been calling me since last year. I reported it to the Federal Communication and still I am getting those stupid calls.

this company calls me every day and never leaves a message, it is horribly annoying......i am sure its just another scam form some idiot thinking every one is retarted!

Called telling me that I won a target gift card, I live in italy so I find that hard to believe.

I answered and got a recording telling me I had won a $20 Visa gift card.  I chose option 3 to have my phone number removed.  Their computer recited my number back to me and said it was removed from their database.  Let's see if that actually happens!

scammers they all work together they all sound a like no matter where they are calling from

got a call from 856-295-5677 didnt answer  did a reverse search  found wsa something scammer

Just flipped the phone back on the rest for a quick hang up.  Caller ID said Camden, NJ

This company called "WCA Subscibers" is a huge pyramid scheme scam.
They tried to make me fill out all these questioneers and promised me rewards.
but they didnt give me anything and kept harrassing me calling me everyday.
I hope someone catches these people.
