Dishonest dealings

I joined dstv multichoice and app**** for price lock,what I understand about price lock is that the money I am required to pay doesn’t change or flactuate it remains the same and that’s why I joined as I needed Explora. It was smooth at the beginning but I noticed that they started taking more money and I was paying the full bouquet price when I am actually on Compact. When ever I try to reach them and call them and ask why this is they try to explain themselves but they also use business jargon and I never really quiet get the answer I need I event DM’d them and this happened again. The last time I called they said they would give me back the money that they had taken and it would take 2-5 working days and it’s been two weeks with no progress. Multichoice doesn’t give a damn about their customer they lack customer service and all they care about is money, they are not interested in catering for the grievances of their customers, so after this price lock I will no longer be interested in continuing my relationship with dstv multichoice goin tv forward because they are proving to be more trouble than they are worth.
