Disconnecting of DSTV

MY DSTV was disconnected although I made the payment in time. Trying to get through to them is a nightmare. They requested that I email the proof of payment to an email address that no longer exist. I email the proof of payment to an alternative email address, but the query was not resolved as yet. This is the second time that the DSTV signal was disconnected this month. You try for days to get through to them. What is the point of paying your account if you can not watch DSTV. The consultant just told me the payment is unallocated and I have to email the proof again. The email address that the consultant provided this morning once again does not exist. This is the first month that I'm having this problem. What is the use of having a reference number on your payment if you have to send the proof of payment to them every month. The consultants at the call centre are uninformed of the selected email address that does not exist and give the clients, that have the same problem, the incorrect information.
