If you have these calls on your cell phone, it's possible that you can get it blocked.

Company called K.E.M Services.. they try to sell you stuff based on your credit card info. They have legit info, how I dont know... When u pressure them for info, they just hang up.

K.E.M. Services either just hangs up on you when you pick up or if they don't hang up, they try to get more personal info out of you by offering to send you free stuff (a $50 gas card and free coffee in my case).  This is a ruse to get ore personal info out of you by getting your bank account information and a confirmation of an address.  How do these people live with themselves?

Recieving at least two calls per day, when picked up no answers. Just hungs up.

10/8 8:48am,, 10/7 8:49am,, 10/6 9:51am,, I work until late at night, so I try to sleep in a little. This is getting really annoying. I only rings once or twice, if I answer, no one's there. Somebody get these jerks!! :)

"K.E.M. Services" either just hangs up on me when I pick up or if they don't hang up, they offer to send me free stuff (today, it was a $50 gas card and free coffee) for being in good standing with my credit card. Then, they try to get me to confirm some personal info like my address and to get me to give them bank information to pay for the shipping of said "free items".  I'm on the Do Not Call registry.  Also, when I block their phone number, they find me again with a different number.  These people are crooked.

They use to call all the time for my wife, They stopped, NOW they called today and A guy was talking to me. Said they are K.E.M Services and they are a rewards program. Told them that this is my number Not hers. Tried to get what the KEM stood for, he hung up... like they used to

so i called and a woman answered asked what they did be/ i didnt understand what biz, she said hold on and hung up. I called back she said it was KEM Services (i asked how to spell it) then i asked what they did she said they "reward" customers who are in good standing

Recieved several calls, pick up and no answer.

Caller knew the last 4 digits of my credit card number, plus home address. Offered 4 bags of coffee for "free" trial to coffee subscription service. Also offered two "free" $50 gas cards, but I didn't get that far. Seemed fishy from the start, but I was interested to figure out what the angle (scam) was without forfeiting any information. Caller completely lost his cool and hung up on me as soon as I said I wasn't interested. Definitely not legit whatever it is.

Twice a day I receive phone calls from this number.  This has been going on for the past three months.  The caller never identify who is calling.  They just remain silent.  Very annoying.  My caller ID reads as 800 service number.

Caller acts as if they are calling from one of my credit cards, they even have the last 4 digits and expiration date, when questioned if they are from that company or to be taken off their calling list they hang up

Someone always asks for Francine. I get about a call a day, always from an 877 number.
