I got the same call and they have been calling every day for three days- each time i miss the call - what do you mean change your card- what card? checking credit?? what do you mean?????????
Seriously? I've been called by this number twice in one day. I would call it back, and even located it down in Jacksonville, FL as a Sprint Spectrum LC provider. For the past 3-4 months it's also been connecting my Mom's home phone and would just hang up, no message. I think it's just spam, honestly.
