Who called from 7707650507

Very rude group of people calling to sell extended vehicle warranties.  As soon as you speak they are belligerent and hang up.

Calling about my vehicle's warranty and they got my personal cell phone number somehow

I answer the call, and if I don't say anything they will not say anything.  I have asked to be removed from their number, but they call anyway.

I cannot get these people to stop calling me.  I have asked politely and they continue to hang up on me.  They are trying to sell shady aftermarket car warranties.  This operation needs to be shut down.
