Dstv is continuing *****ing from me

I checked my march statement on dstv app on the 28th February as my debit takes place on the 27th, I realized that for March they charged my twice for internet I called them they told me it will be rectified the next day guess what it's the 3rd and still nothing was done on top of that I've been calling them from December to remove Netflix that I didn't authorize they never did in January they added that R199 to my debit order and took. I called them again and they promised to refund me guess what they refunded R20 instead of R200. Every time I call they tell me it will be resolved within 48 hours now it's 3 lonths later they're now charging me double for internet and it seems they not willing to fix this mess they just want to continue *****ing from me every month. I reported this on hellopeter last week agen sent private message said they'll fix it as always empty promises since December. Are they really people working at dstv or dstv is on auto pilot? With this level of incompetence I don't think anyone is doing their work there ,the only work they doing is *****ing from customers
