This is USAA.  They actually gave me this number to call regarding some issues in their collections practices which I believe violate FDCPA.

Calls multiple times per day.

i get 7 to 10 times per day

This number called my husband but he ignored it. He called her back and she wanted his name, number, and his SS# because she "didn't know what she was calling him about". He refused to give her information since every time he called USAA he would get the automated system, and not a real person until he went through the system. She said to "go ahead and call the main number". He did, and talked to a representative. She said that NOBODY would ever call him [especially the collections department until he was 30 days past due], and they automatically would have his info and what they would want to call him about. So all in all, USAA told my husband that this was a PHISHING call and that they are aware of it. DO NOT give information to this person. Make sure you call the REAL USAA number before you give information.

No message left... Must have been USAA like you guys said above...

Call was ignored. No message left.

USAA Banking Services (as an unknown caller).  Leaves no message.
