Bad service and customer ******* and **************

This was the biggest level of bad service received ever. I have contract sim with Telkom the sim card for data I had a problem with it and contacted Mondo which was also responsible for that promotion. That sim card I am unable to make calls with even their careline free number .I went to centurion Telkom the consultant told to do sim swap and see what happens there after. I printed Telkom statement as it has proof of address and went to Telkom Mam's mall after waiting for 45minutes there their consultant told me that they don't accept their invoices as proof of residents my first what does Rica law says? Secondly I did not see a big board written no Telkom invoices accepted as proof of residents . Does Rica approve such nonsense? Now telkom and Mondo are busy debiting my account for this nonsense where I can't even get clarity why am I experiencing this nonsense service and it can't work even if on roaming .I have messenger texts with Mondo sending me from pillar to post this worse than toilet **** service.
