Caller ID read "Frisco TX" which is a city north of me.  I did not answer, no message left. Now blocked with Ooma.

Tried to convinve me they were from Mercedies

"Certified Pre-Owned Warranty Department" called me, trying to sell me an extended warranty. I asked what company he is with. He just kept saying "Warranty Department". I told him he is mistaken because I have an extended warranty, had service last week and my warranty is not expired. Then told him not to call me any more. He started his tale ... in order for me to stop calling, I need the mileage on your vehicle. I told him to buzz off and hung up while he was still talking. Jut another scammer trying to sell something you don't need.

Telemarketer of some call center type, dropped a curse word and hung up

Got this call. no one left a message.
