Why do these people keep calling my cell phone?

In the last week, this auto insurance place has called 9 times. They keep asking for someone who I dont know. I've told them to stop calling because you have the wrong number, but they are still calling! I sat on the phone while they were talking to me, saying they were removing me from the list to call. Why won't the stop calling?

do you have there number or is a private call? it could be people prank calling. I keep getting text messages for a website where you get any meds with no perskription. companies AREN'T allowed to call cell phones only home phones.

Actually companies can call your cell, just not for solicitation purposes. Odds are maybe the person they're calling owes them money. I have the same problem... the guy who had my number before owed a lot of people money. One time someone actually questioned if I was lying to them about knowing him (yeah he wont be doing that again)
Maybe try calling them back and explaining that you arent the person and they have the wrong number.
If it doesnt work try calling your cell company and getting their number blocked
