Unknown caller, no voicemail

This some refinance place. I decided to answer because I am getting sick of these calls. The idiot who answered claimed I had requested refinancing my home. And he called me by my first time. I told him I had not requested refinancing and he argued with me, claiming I had and he had it right in front of him. I was very nasty to him. I told him it wasn't me and if I were refinancing I'd be using my own credit union and not some random place in California or wherever it was. Dumb [***]. I'm going to keep answering these random calls now and just be a real [***] head because the do not call registry does not work.

CID said SANTA ANA CA. I didn't answer--they didn't leave msg.

Doesn't leave a mssg and if you call back you cannot leave a voicemail--says the mailbox is full when try to call it back.  We did just recently refinance our home through a specific company, but not sure if something goes out during the process that alerts other companies, but would never trust a company that does not have a solid call back business number (or one that I did not choose to call anyway).

I'm fed up too. If I'm here I may answer, depending upon my mood - bad mood, answering and arguing. Good mood, ignoring and reporting. If they hang up , reporting and blocking, fighting back.
