Dstv incorrect billing and cancellation of my pricelock without my knowledge

Good day

I have a problem with dstv MultiChoice am a pricelock customer on compact paying R423.00 per month and all of a sudden today when a log into the dstv app I saw my bill being R866.13. When I call dstv I was given different versions as to what happened to my account,the 1st version was that the premium for June was reversed back to my account which I explained that I didn't receive that reversal in my account,when I was trying to find clarity they gave me the 2nd version which is that my pricelock was cancelled on the 16th of June and that was done without my knowledge and now they are telling me about arears related to confection free which I don't understand,the matter was transferred to another department whereby I was promised that I will be called in 30minutes to resolve the matter but when I was called there was a lot of stories that I was told and second time I was promised that I will be called by 10h30 today with the feed back as to what happened. I want to know who cancelled my pricelock based on what and let them reactivate my pricelock because cancellations was done without my knowledge it feels like am being taken advantage of.

Hoping for your positive feedback.
