Just another stupid robodialing crook. If they don't have time to talk right then, the machine just hangs up. What a bunch of crap. If you're on the "Do no call registry" it's illegal, but they don't give a damn because nobody enforces it. Just block it and report the violation, for all the good it will do.
If you have given them your credit number, call your card provider right away to protest any charge and get a new card number. It's a SCAM.
In broken English the man was questioning my vehicles warranty. I asked who he was calling from, because i do have an extended warranty, and he said they handle all Toyota warranties. When I said I had already one he told me good bye. He was nice at least.
