I was at work, it went to vm. No message left

The automated recording said that it was from the credit card company but they did not say which one. I waited and asked the guy(with a thick accent) which credit card? He replied with all of the major cards. I demanded that he leave me alone and he hung up. I called the number back and the message said that it was a disconnected line. Its a fake recording. The phone company always repeats the number that you dialed before it says "disconnected". Phone scam if ever I saw one.

Same guy is calling my 14 year olds cell and wont remove her number from the calling list.  What does that say about him that he want to keep my daughters cell number?  CREEPY

answered call but hung up.

Received call saying that he represented all credit card companies and was able to reduce my interest rate to 6.99%.  I asked the name of the company, he says 'Customer Card Services' located in Orlando, Fl (and others).  I asked for information to be emailed to me so I can review to see if this was a scam. He said OK he will email it to me and then hung up. Funny thing is I never gave him my email address.  I called back and it was a disconnected number.
