BILLING ERROR STILL UNRESOLVED

good day

I was offered a package from multichoice of R499 price lock, it was on a special. a couple of months passed by and all was well until last month were I was overcharged R2145.00 from my account. next day I did a reversal from my bank and did an eft payment of R570 which includes the decorder insurance and the box office rental.

my debit order on the price lock is always on the 25th of every month but some how I got disconnected on the 22 of October 2019 when I had made a payment that covers the whole month on the 26th of September.

reason I was disconnected is because they say I am outstanding an amount of R754. I fail to understand why they cant fix this issue after numeral calls I have made these past couple days no one seems to help. as far as I know the agreement I had was for price lock for the price of R499 a month but here I am being told I owe R754, till now nothing has been resolved and my debit takes place tomorrow. we work hard for this money and all multichoice is adding more depression in my life on top of other issues I have to endure daily
