Disgusting Client service

For more years than I care to remember I have paid my TV license timeously each year.I have for many years trying to get the SABC to update and correct my account with them, without success.( I eventually gave up ) This has transpired over a period exceeding 10-15 years, and I have all the documentation to prove it. Their latest trick to is use a company called MBD ( ********** 673 ) who harass you on a daily basis with SMS`s.Up until the middle of December 2017 I deleted them, then I thought I would store them to see how many I got.( 15 so far over 3 weeks ) I now receive one daily !!!! Is this not harassment, and can it be challenged in court ?? Clearly, in my opinion, this company is in it for the money and bill the SABC continuously for these SMS`s.( which we pay for ! ) I even got shouted at by one of their staff, without even listening to my explanation, so I cut the call. I cannot talk to rude and arrogant people. When an organization cant get their own house in order, how do they expect to operate properly ??? Apparently I owe them money dating back to 2000 !!!!! Incidentally, the SABC don`t even know how many account numbers I have with them !!! Cleaver hey.. But they still get this company MBD to harass you. So to all those people out there with SABC and MBD problems, you are not alone.
