Worst service ever

DSTV account was registerd on my Late dad's name, but debit order was always done on my mother's account. All i wanted to do was to change account into my Mom's name. Spoke to Daniel at call centre who asked for a letter of Executors which i send through for change of ownwership. Daniel then promised me a manager will call me same day and no one called. Change of ownership was done but connection to DSTV was interupted, I then called again and was transfered to team leader Lashen Naidu. I explained to him that the debit order went through on the 1st but no connection to live TV, he asked me to send him through proof of debit order which i did send a bank statement to him. He never acknowledge reciept of email no has gotten back to me with feedback. I emailed him again this morning still nothing. Also i have been using oline chat with Ntswaki and Nompumelelo. Nompumelelo said she was escalating the issue to management that will contact me. still no feedback. All i asked for was change of ownership with same bank details for debit order. This exercise caused so much confusion on their side. And the debit order has gone through. Please get back to me urgently.
