Dstv is a waste of time and money

I have spent over an hour on my cellphone at my airtime cost trying to sort out an error . I have called them 4 times and now my dstv is not working at all after speaking to them and now I must pay to get an installer after the person at the call center advise me what to do and now it is completely not working. I spend nearly R1000.00 a month to watch repeats. I am not happy with dstv and want to cancel my subscription after being a dstv member for years.
