Received calls two days in a row.  Caller id says ntl dealer service

CID says NTL Dealer SVC. No message left. Blocked them now.

Thisi number calls daily and never leaves a message on machine. Today I answered and guy asked for my husband. Told him husband is not available and asked him who he was with. He said Vehicle Processing Center. Since our cars are paid off, I asked him what this call was regarding and he hung up.  I called it back and it's a recording saying if you want to be on a no call list from this number, to hit 1.
