Poor service

My payment date was changed without my knowledge from the 26th to the 15th and when I called them no one can tell me why it was changed to the 15th, now I keep on being charged a reconnection fee this is the second time this fee is being charged, I called on the 30th of august to raise a complaint and I was promised that someone will return to me in 76 hours, even today no one came back to me to explain what happened, they don’t even have a call log that showed that I called in to change the date but yet the date has been changed, my subscription was disabled this morning and I was told to pay R127,23 to watch until the 26th and I have to pay again my subscription fee and reconnection fee on the 26th as per the amount due, no one can tell me why I keep on being charged this reconnection fee, this is getting frustrating I cannot keep on doing this every month
