Called with the caller ID of 'Wireless Caller', left no message.

It was a recoded message talking about lowering credit card rates.  I filed an online DNC complaint.

I have gotten calls at my place of work (I answer the phones) for months now from this number. The pre-recorded messages says that it's Account Services calling to lower my interest rate on my credit card. Every time I pressed the option to be removed from the list it did nothing. So I started pressing 1 to talk to a representative. When I asked what company, they hung up. Then I started saying "I have many credit cards, which one are you calling about" and they said "All of them maam, we service all Visa and Master cards." and I asked again for the company name and they said "Account Services." When I asked what number I could return the call to they hung up on me. So the next time I asked for a supervisor. He was very agitated with my questions (really, you are going to ask for my credit card account numbers and get testy with me when I want to know who EXACTLY you are???) and said he would only provide company contact information IF I provided credit card information. Then he hung up on me too because I refused. I plan to file a report federally and locally in MN, I encourage everyone to do this.

I have been scammed by this number once, claiming they were giving 50 dollar gift cards. Like a dummy I followed through with them, then immediately called my credit card co. and asked them were they giving the gift cards. They said no. So I canceled my card before they could take anything out. now about an hour ago I got a call from this number, claiming to lower interest rates, so I also pushed 1 and was connected to the same lady that scammed me before. I asked her which card she was calling about, and what was my number, she hung up quick. These people are scammers, do not give any information at all.
