I got a call from this cell number asking for my credit card number and saying they could reduce my interest rate. I think this was a scam or attempt to use my info fraudulantly

This number left a message on my answering machine Yesterday at 5:45 PM EST.  There was only half a word on the machine so it must have been a prerecorded message that ended as the answering machine was starting to record.

Scam with offer to reduce credit card rates if balance is over $3000.00.  Wish I knew the identity of the company calling, of course the message never provides that information.

I got a call from 415-244-7745, and same thing; no message. I don't answer #s I don't recognize anyway, but damn, it is annoying! I'm on the do not call list, and have had too many of these type calls, and report every one of them, as well as do a *57 trace to the police on them. There are SO many scams out there today, it's sad..best thing to do is not answer any call you don't know the # to, want to. It's sad that we have to do that but that really is the only solution I see.
And this comes a few days after this other co. calls me and family and friends of mine and tries to extort money from me! I SO hope they're caught and I will pursue them legally nonstop once the police, FBI, IC3, and/or secret service find them. Definitely report these scammers, I am; strength in numbers!
