Disastrous DSTV service

Dstv customer support is a complete disaster! My father passed away almost 4 months ago. In order to streamline processes for my mother to continue having access to DSTV, and to ensure that we transferred everything before his bank accounts were frozen, I phoned to find out what the requirements were to transfer the account to my mother. I filled out all the forms - including the block where the deceased has to give permission for the transfer, sent all the documents back, only to be told they now could not process until they had the letter of executorship - this in spite of having a death certificate amongst the multiple documents submitted! More than thirty - let me repeat that - thirty emails later, we are still unable to transfer the account. They have now cancelled my dad's subscription - only because his bank account was frozen. My mother is still unable to access in spite of more phone calls, making payment etc. All we have is yet another email asking for all the documents already sent a number of times. I even tried the WhatsApp bot this morning and went around in circles. What a completely useless company.
