DStv

I would like to log a complaint against DStv who want me to pay again when i already paid my account. Ever since i cancelled Price Lock i am experiencing problems every month with my account. I have asked please put one decoder on Family and the other on Easyview, then i discovered that they have put the wrong decoder on Family and disconnected to right one. Then they put the wrong decoder on Easyview and the other on Family. So I asked them to fix it, they said the system is giving them problems. So by mistake in May i did a mistake and asked them to downgrade one decoder to Easyview. Now they want me to pay for something that i did in May. They disconnected one decoder and i only watced on the one decoder. How can they expect me to pay for something i didn't watch. Now one decoder is on Easyview and the other is disconnected. They expect me to pay R353 for family to be activated. When i already paid R372 with insurance. They expect me to pay again. When I asked to fix this they said they going to escalate the matter as they can not do what i need
