Bad Customer service and experience

I have been on DSTV premium for over 10 years now and it's the firat time where my debit order bounced with money in the account and I was expecting for them to take R988 and they wanted to take R1900 and they are telling me that it's due to the internet package. I was not informed that they will be taking R1900, they had a special that included data and that's what I asked for and the amount was definitely not R1900. if you check their promotion pamphlet it said R899. So the maximum i expected for them to take was a R1000 because of insurance. Now they have switched off my dstv premium package, I have called over 10 times, complaining about this and they switch it on and then off after a day. We told them to cancel the data package because it has never worked. The only person who understood was Rosetta Mhlongo. She told me she will calculate how i would need to pay via eft of R709 but i paid R800. I am extremely disappointed and will be cancelling everything if they do not restore my services and I will spread the word... I'm quite big on socialedia and have over 500k followers. Dstv has been all over news papers and social media about losing premium package customers, I understand why and soon I will follow. For a person who has been with you for over 10 years on premium, you have shown that you do not value my business.
