Who called from 2132211021

I received number off calls over the last few months and when answered they hung up.

Carpet cleaning ad.  Man identified company as "Best Carpet".  When I asked for the address, he hung up.

I tried to block this number and my service cannot. I am on the DO NOT CALL LIST. How do I get this business in trouble? They have called numerous times

Have received calls from this number several times a week. They leave no message when the machine picks up the phone. I'm on the DO NOT CALL list.

Their "direct" number is 888 279 6054. The person on the other line states she is not in the United States and does not care if she is in violation. She started mocking everytime I stated to her in a singsong voice. I'm filing and I hope if you're on the Do Not Call list, you do as well.
