Cancelling DStv: Good advice

Early December 2018 I cancelled my DStv subscription. I didn't want to waste time going through the call-centre, so I used the online option. Took me a while to figure that one out, but eventually cancelled my service. Sadly, they don't give a reference number. My subscription was suppose to be terminated January 1st (there is a dropdown box). So come January 1st my service is still up and running. And surprise surprise on January 2rd the R899 debit order went through. So I did what I didn't want to do in the first place: call the service centre. 20 minutes later I was told there are no record of me cancelling my account OR me logging into my account. Strange, since I logged in multiple times on the app and PC... Anyway, long story shory I have to pay an extra month for a service I don't want and hopefully the service will be cancelled February 1st (got a refence number this time). So if you want to cancel DStv, take the time and go through the call-centre. Waste of time, but it will save you money.
