Scammers

This call center constantly calls me even though I have begged them to remove me from their call list.

They alos go by the name of Blu Credit amongst others. I believe they are situated at 75 Grayston Ave in Sandton. It looks like there is no business at this address. They call from: 0873302598' 0115956521, 0115956581, 0115956530, 0115956502, 0115956587, 0115956545, 0115956582, 0115956584. Can any body please give me the owners name, phone number and address so that I can go there and confront this a hole please?
