Multichoice(DSTV) fails their customers

I've paid on their absa account using mobile app banking then i attached a proof of payment and send it to their email address(***), then they reconnected my account but two days later they disconnected my account telling me i didn't pay. Then i called their call centre and emailed my proof of payment again and even went to their brach at maponya mall with the same proof of payments and within a week of doing they closed my accounts again. Please Hello Peter help me
