No help... yet I pay!

I have been receiving messages from Multichoice since January 2019, stating that if I make my payments on time for the next 3 months then my subscription for the month of May 2019 will be paid for by Multichoice. It's been 3 weeks now and I have been having numerous problems with Multichoice due to the fact that no one in Multichoice has loaded my discount for the month of May 2019 and I keep getting sms''s to say your account has been blocked and with each sms there interest added to my normal subscription. I have called multichoice over 10 times and every time I called them and the consultants say they are going to escalate the discount to the it and finance dept and my account will be credited with the discount but the very next day the account is blocked again and then I call again and the same thing happens and furthermore every consultant has a different excuse as to why the discount was not credited to my account. I have already spent 200 on airtime just calling multichoice that's already half my normal subscription. Someone from the finance dept was supposed to have called my the 24.05.2019 but no has, I was also told on the 24.05.2019 when I called Multichoice again that it'll take 24 hours turnaround time to rectify the problem. I called in at 5 pm on the 24.05.2019 and I was told it'll take another 24 hours to rectify because the person whom I called on the 23.05.2019 did not escalate the problem I am having to anyone who would have helped me and maybe that's the reason no one called me.
