Joe has hit the nail on the head. Computer running thru banks of phone numbers hoping to snag a "live one". Its really simple, if you dont recognize the number, dont answer.
I got a call from same number, asking about car warranty about to expire??? I ride a 66cc bicycle how is it my warranty is about to expire i built the Da#* thing. if it breaks i will fix it.
This phone number called me asking about my expired warranty. It directed me to press one to get more information and then hung up. 2 mins. later another number 207-221-0506 called me asking me about my car warranty. I asked what car she was asking about and she said your car year 2003-2010. I told her I didn't have a car in those year. So, she must have not know anything about my car. These is okay a telemarketing/scam/annoyances. Block their number.
