DSTV lacking customer service

I have been a loyal subscriber for about 20 years. A few times over the past few months we have been charged for box office movies that we did not rent. I have asked them repeatedly to look into why this glitch is happening. Previously they reversed the charges. But not the last one! It was almost impossible to get hold of the call center and i probably spent more money holding than the movie would've cost. I emailed twice before I got a response. Only to be told that I did rent the movie when I damn well know I didn't. I was told it wasn't a glitch in your system that I rented it and weren't even prepared to hear that it could in fact be a glitch . So therefore would not reverse the charges. Multichoice, billing someone for something they didn't order and refusing to reverse the charge is theft. Telling them they did when they didn't is insulting. You lost a monthly subscription of over R1000 for trying to force me to pay for something I didn't want or order. So please cut me off, you will never see another cent from me. Not even for the movie I didn't rent! It's very disappointing to be treated like this after so many years of subscription. You have left me no choice but to cancel the subscription. I won't be charged for something I didn't order and you aren't even prepared to look into it to why we are being charges in order to guarantee it won't happen again.
