Cannot fix an error that they made

I previously had 2 decoders in my name that I was paying for, one for me and the other one for my parents. In 2014, my husband and I went to their service centre in Randburg to purchase an exploration. We asked the person helping us to put the new explora in my husband name, and to leave my parents decoder in my name. We found out months later that the change in ownership was processed incorrectly and phoned to get them to fix the error - nothing came of this. So today we finally had time to go back to the service centre to fix the error - we were told that the error cannot be fixed, we need to complete new change of ownership forms again!!! . Further to this the insurance that we had cannot carry over for a reason that they cannot explain , and must be cancelled and another 3 month claim waiting period will start!!!! Really, for an error made by them - I asked them to pull the records of the previous chanting ownership form and I was told that they changed systems and don't know what happened to then - I asked who can tell me and she said only the person who processed them can tell me - what king of service is this. When I asked to speak to a manager, a very arrogant lady came and spoke to me Honestly I am very dissatisfied with the service that I received An error made by them cannot be fixed- how can this be I'm appauled by the service from Dstv
