Poor customer service from Dstv

yesterday Monday 4th of October 2021 my dad made a typo on his capitec banking app whilst paying for his dstv account he was supposed to pay R427.03 instead he paid R4270.03 l immediately went to Twitter we're l wasn't satisfied with their reply tgen l went to tge help email sent them proof of payment and told them the mistake that was done and that l wanted a reversal of the money back into his account - the subscription made . l even went to Capitec Rustenburg Mall with my dad and there we got a proof of hard copy went with it to Zinnavile Dstv Agency and we were told we also had to bring Bank statement . Today l am at Zinnavile again still waiting to be served but the person who served is still busy with other duties and lm sure l will wait long hours lm afraid they will close and l haven't gotten what I need or they will tell me another story my dad is busy at work he won't get off for a long time from now and that money we might lose it lm so stressed l don't know what to do anymore
