The exact same thing happens to me. For the last two weeks or so I've been getting a call from this number at least once or twice per day - usually with no response on the other end of the line. This morning was the first time someone spoke when I picked up, asking if I was a sufferer of chronic pain. Now I can officially know to block this number in my phone.
These people called me on a very private cell phone - I could not understand the person - they were from a foreign country. India?? I told then to remover the number and that I am going to report them. - I said take my number off the list or you will regret this call!!
They knew what car i had and said they were calling from the warranty department, the idiots didnt know i have mopar extended warranty. So they call pretending to be your warranty so they wont even say the name.
