Same here.  Get calls from this number daily.  They never leave a message.   I'm on the do not call list also but since registering with them I get more of these type of calls than before.   DO NOT CALL LIST doesn't work.

received several calls from 500 Fast Cash, the numbers are 800-318-9902, 800-420-3194,
800-359-4872. on the week of april14th, i received an email stating that i owe, my response was to send me a written letter by mail, stating the debtor, amount, acct # and their address. today is April 23rd, and yet no response whatsoever.  

Constantly calling my unused house phone. Leaves a silent voicemail. Calls every day at least two times a dah

(800) 318-9902         These calls come in daily.

 I learned they are from "  500 Fast Cash  "   lenders

  They threaten to have you arrested in 48 hours.         Pakistan group I believe .

Robocall saying the name of employee who gets calls from payday lenders. Gave this callback number: 800 359 4872
Too bad payday loans are illegal in this state and cannot be collected.

Keep getting calls its a recording to call back differents each time so call  back woman says he from FCC, and asked who the call was for and she said it was private just need to verify personal information. I  asked why I keep getting called and to call back  different numbers each  time she  claims I shouldn't be so  I told her that person doesn't  live here and don't know them, she is suppose to take care  of this  let's see.  So fed  up  with these idiots.

keep getting calls from this number, I dont answer calls I dont know. Dont know who it is but I am on the do not call registry

Jerks call everyday at all hours of the day from Fast Cash Collections Department. This is a brand new cell number I am reporting them to the Federal Trade Commission for harassment! I suggest you do the same!!!

called again today.  Again a pause after I picked up.  Call was transferred. Male with Pakistani or Indian accent asked for a subject by name.  When told that they had wrong number, said "come on buddy put her on" again told that the phone number is no longer hers told me to give  him the new number.  When I told him no he demanded my name and when asked his again insisted on mine and when asked his company again demanded my name.  At that point he was told in no uncertain terms what he could do to my royal backside and  hung up on.

Called left msg  asked for a person with an oriental sounding name, spoke fast  so not sure who they asked for.  
As they were asking  a voice recording came on telling my voice mail to wait for an available operator.
Obviously spam.

The number is for 500 Fast Cash
