they called and wanted me to confirm the last 4 digits of my credit card. When I did this, then they wanted the security code. I declined and they hung up/ Weird!

I could barely hear them.  They asked for me by name and then the call cut off.

Same thing here.  They've called twice today.  The first time there wasn't anyone on the other side.  The second time they asked for me by name and the call was cut off.
