Worse customer service ever

Today I received the most terrible customer service ever from DSTV 031 customer care, i spoke to 6 + agents and not even one of them was able to assist us. On my the 3.11.2020 the system said we owe R548.96 when I checked today it said we owe R955.88 we spoke to one of the consultants and he said its a system error he said we must pay R452. We immediately made an EFT payment of R460 however we still not connect, the agents keep dropping my calls as am explaining the same thing over and over again, one of the agents made me wait for over 9 minutes i had to drop the call as my airtime was getting finished, i asked to speak to the Supervisor or Manager and we waited on the line and we was told he is busy with his team. What type of service is this, how are agents not able to assist us. What did i do to be treated like this. If agents cant assist us than who is to assist us.

I would like to be contacted and also complain about the agents who wasted my time.
