A birage of numbers form the same area code and 918 numbers who belong to paying cell phone customers tieing into these just to get you to answer for a supposed vehicle warranty expiration then asking for details about you and your vehicle. My advice? Keep calling them back and making their live hell.... bullcrap! We work too hard to have a constant blow up if our phones.. you'd think the carriers would have deciphered and used a permanent blocking program to keep it for happening but NO!!!
