I received a call from CARD Services, yesterday and today. I selected the option to be removed from their mailing list and still, I received another call.  Could be a SCAM.

Call asking to reduce my credit card interest rate to 0 to 6%,  asking for my outstanding credit card debt.  They claimed they were from Financial Card Services and that I could look them up on the better business bureau.  By they way they offered this information up, I could tell that this was absolutely a scam.  
When I said that I had no outstanding credit card ballance, they hung up.

Have received multiple calls from these clowns at my work (direct dial) number. Doubt
very much that they got my number from a list since it is new and unpublished. I have now blocked the number.

I just got a call from this number on my work line. I hit #1, and someone answered saying it was "Card Services."  I politely said that I wasn't sure what business this was, but I wanted my number taken off the list, and I was hung up on.  I went to call the number back, and it says it's disconnected.  Obviously a scam.
