Asians selling drugs. Calling constantly even though we are on the "do not call" list. Need to block this number.

Had more than 9 calls in one day. When I ansered they said  they were shipping my order for some pills. I let them know right away I did not order them and they needed to cancel any thing they were trying to ship to me.They even told me my credit card had already been billd 240.00.I told them I would call my credit card company and have it removed.There was no charge on the card they were fishing.Probably the next question they would ask would be to verify my credit card number. NO WAY
