Worst Service Ever

We took up a payment plan in December 2015 on Pricelock with DSTV Multichoice, they were supposed to debit my mom who is the account holder's bank account which was then with Standard Bank. They failed to take the debits even though we provided for the monthly installments of R529.00 no debits were ever taken of her account. After numerous phone calls and trying to get a hold of someone who even gives a **** in that company we finally managed to make a payment arrangement in August 2017. Although we have been making the following payments... R 1500.00 in May 2017, R 1000.00 in June 2017, R 950.00 on the 2nd of August 2017, R 850.00 on the 31st of August 2017, R 750.00 on the 27th of September and again R 750.00 on the 26th of October. Our services are disconnected on a daily basis since the 2nd of November and I've spent more time on the phone to them than actually phoning people I care about, every time I phone, services are reconnected and I'm told that our problem will be escalated to the DPP department , they the DPP department was supposedly going to phone me back at 15H00 today. Why have I not received any calls??? Your Service Sucks!!!!
