Admitted to overcharging by double by call centre no credit reflect new bill wants to overcharge by 3 times the monthly amount

I am being overcharged as per the lady I spoke to Sunday, you have charged me double n now the new bill is triple the amount. I called numerous times and finally a young lady from price lock called back, found out that I was double charged said I would be credited. No credit reflects in fact now you want to triple charge me. I get debited have never been late on a payment so why do you do this. She said the bill for Feb does not have a code yet so it can't be changed nonsense. January they said it would change after 15th too it didn't and you took the money as per the amount on my dstv app. I can't download statements on my dstv as your system has an error. You are robbing me blind n all you want to do is credit. I want a manager to call me n email me all my statements. Give me written proof of this credit and that the problem on my account has been fixed n I won't be overcharged or I will take my bank statements forward it to the ombudsman and a lawyer. I'm tired of the ****!!!!!!!next you can just charge me 5 times the cost n want to credit me but I need the money for my family n won't by then get a refund either
