DSTV Customer Service Bad Service

My Mother were forced to upgrade her DSTV package to the Compact Plus package before 1 Oct 2019, which she did on 24 October 2019. The customer service agent said they would adjust her debit order. 1 October 2019 the old package's premium went through and the disconnected her services. 13 October 2019 she receives a message stating she need to pay the difference into their account which she did and the proof of payment were sent to *** and ***, after phoning the customer service the same day they eventually received the proof of payment. 17 October they disconnected the service again and again the proof of payment needed to be email and searched for again - reconnected again. On 23 October disconnected again, spoke to managers and customer services and emailed the proof of payment again, promises made they will allocate the payment - connected again. Today 28 October 2019 disconnected again stating the payment STILL OUTSTANDING phone customer service again, selecting the customer service option NO ANSWER.
