I had two telephone calls from this number on a telephone I use as pre paid essentially for emergencies
and I happened to be in the public library where I am not allowed to use a cell phone, THANKS!

It's rewards660 credit card's customer service. You must have had a late bill.

Just got a call, answered and heard nothing. I hit redial and heard a recorded message... "we're sorry, the number you have dialed is not a working number".

Received another call today with pre-recorded message regarding a rewards card and asked that I contact 866-838-6102. Called the number and heard another pre-recorded message from Rewards660. Late bill you say?...How do you know I have a credit card?? Never assume anything.

Recieved a call from 205-469-3621 telling me to call back 1-800-635-4713.
I don't write a checks so I know there was no bounce. When I called back the 800 number I was presented with entering a code or my checking account number (not a chance). I entered random numbers until they answered with a non professional "Hello". I asked to speak with a fraud department and they said that they "Don't have a phone number, only an address to write".

I will be calling my phone provider to have their number blocked.
