*********** staff & useless automated systems

I am so annoyed that I must be put out of pocket because DSTV has *********** staff and automated systems that don't work properly. I requested for my package to be upgraded due to the Rugby but clearly requested that it be downgraded again by 28 October. On 25th my debit order went off for the full package . I called in and was cut off twice so I decided to use their watsapp facility. After a few attempts to downgrade I got a response "Thank you, this change has been scheduled. We have scheduled your downgrade from DSTV Premium to DSTV Compact". Today I get a sms to advise I have been disconnected. When I call in to make enquiries I am told I must pay R889.60 compared to R539.00 and they cant downgrade me until the 25th. I don't have R889.00 to pay DSTV but because somebody didn't carry out an instruction properly I am supposed to pay it,to be connected. When I tell them I did request this twice already he says there is nothing he can do I must pay it. When I ask to speak to a supervisor I am told they in a meeting , I can call back they open till 11pm. What
