Got a call from this number on my cell but missed the call (about 10 AM on a weekday morning, probably expecting a retired person to answer). Did not leave a voicemail.
All you can do is file a complaint with the do not call people. Takes less than 20 seconds. You don't need to fill out the comments section or give personal information. Only by reporting can these people be fined and stopped.
Called and wants to talk to me about lowering my interest rates on my credit card VISA with Chase, Wells Fargo, and/or Bank of America. When I said hmmm, I'm puzzled as I don't have a credit card :) They hung up swiftly.
