Repeatedly calls, no one answers when I pick up.

No message

Unknown number so I didn't answer and they didn't leave a message.  Safe bet that it was a bogus call.

Extended car warranty scam. They try to pretend they're your car's manufacturer.

Same old - same old.  I now talk to these idiots and tell them they need to mail me their physical address and financial statements to prove their products are real and the company stands behind them..  It wastes their time and gathers infomrtion which I will use in my class action suit.
