Who called from 7036727875

Robo call from The Tea Party Majority. Hung up on it & blocked.

I received a call from the same number. Only the caller ID said Tea party. I didn't answer the call.

Called today. No message left. CID said CUST SRVC.

Caller ID said "Cust Srvc". Asked for my wife and I hung up. Should have asked what they were calling about but I think it's a political call.

again,  phone rings.  caller ID says Tea Party,   I answer no one talks,   I let ring   no message
