Disgusting DSTV

Disgusted with DSTV, They always send messages reminding me how much they're going to debit on the 25th of every month. Early this month they sent that message again saying they will debit R419. On the 26th I received a notification that they debited R419, on the 27th in the morning I woke up to a message that say my account is suspended due to non payment. I immediately call their customer service and the lady I spoke to confirmed that they did not receive the payment, I need to sebd a proof of payment which I refused to do that. After the call I received another message that was saying thank you for the payment but I'm still short of R50. It confused me what exactly is going on because they debited the exact amount that they promised. Please sort out your accounts division.
