Who called from 9153175207

I have tried to tell them not to call anymore and they hang up on me. Them they turn around and call 4-5 times per day.

Last week they said it was a career advisor, this time an auto warranty protection, I put them on speaker and they hung up.

I am so frustrated with this company and I can tell they're using A voip  and they are not located here and it's jerking the phone into thinking that it's in our area code. I'm about to change my phone number. I can't remember if this is ever happened before and I don't think so. It's all within the last six months - we were always able to count on her cell phones to not have spam
