Who called from 6137845252

Answered this by mistake and it was a company offering 50% off duct cleaning.  I listened to the guy for a bit just to hear what he were offering, but in the end told him I wasn't interested at this time.  He hung up as soon as there was a hint of me saying no, didn't even say goodbye.

Received a call from this number this afternoon. Did not answer; nno message left.

got a call yesterday from this number ...I said hello three times...no response, then an automated and creepy sounding "goodbye" and then it hung up

Received a call from this number just now, no message left, only rang once.
