Bad service from DSTV call centre agents

Customer service agents on *** is absolutely shocking. According to one of them, the DSTV accounting system has an unknown delay with receiving payments from FNB & as a result your service will be suspended regardless if you made payment & sent them proof of payment or not. When I questioned this, no answer was given, only that they have no control over the system. What is the point of sending proof of payment if the payment can't be allocated to your account? When I asked the agent if I can speak to a supervisor, I was placed on hold for longer than 20 min & I eventually had to drop the call. This was done deliberately to get rid of me & my call was not directed to a supervisor.
