MWEB worst ISP

I have had a bad experience in moving to new premises. I have notified MWEB which was supposed to inform Telkom that my line will move and due to the move being more than 10km, my Telkom line number had to change. I have been on a number of telephone calls between Telkom and MWEB since 2 January and have had ZERO success in getting my line active again. The telephone line is active, but no internet or ASDL.... I do not know what to do next!
