Dstv multichoice

Hello Peter. I am an honest client at dstv but recently i am not satisfied with the service from dstv. Last month they billed an extra R10 from my account and i called to find out why. I was told that they will deduct it from july 2020 monthly suscription. And i was promised that in july they will deduct and amount of R849. But they again went to my account for an amount of R898. There were no enough funds in my account for the transaction, because i was promised that i was to pay R849 but then i asked them if I do an eft payment they wont disconect my service. They told me is i do eft payment the very same day mu services wont be disconected. Now my services arr being disconected and if i reconect i jave to pay an amount of R900 and more next month. So in other words i have been paying more every month on dstv and no one from dstv knows why. I asked how much is my monthly susbcription, i was told is R849 per month but i am paying more than that amount without renting any movies from them. So basically is like they disconect my service and reconnect it every month. Maybe thats why i pay more every month. So i want an explanation from the person who is in charge for dstv. I wanna know axactly what is happening in my account. Please Peter assist me with this.
