Who called from 2182030752

Received 2 calls from this number in less than an hour. Some perky irritating voice on the other end insisted I put my number on some call back list for some survey to win money. I did no such thing. From the little searching I've done this is a strong phone scam. I did not give them any information about myself I just sternly asked how they got my number and supposedly it was put in some system to win something of which I did not do. I don't give out my number. I requested they remove my number from their data base. I have also blocked their number from my cell.

I am on the do not call list. Why am I getting phone calls from these people? I do not answer any odd numbers anyhow!

Number called me but I didn't answer and they hung up before getting my voicemail.

They keep calling me and hanging up and i text them and no answer should i call the police

call said get chance at cash drawing for brief survey ...took long time then they wanted my email and hung up before I said it.
