Multichoice taking advantage of their customers

I have a concern.i have been paying dstv through debit order for more than ten years .my debit order goes through on the 26th of every month.This month(July's) debot order also went through on the 26th.i was suprised when i tuned onto tv on Saturday the 28th only to find that my dstv has been disconnected.i later received an sms that status thus We've stopped your DStv as you've not paid. To reconnect, pay R449.00 using ref no.***8. Once paid, we'll reconnect you. To pay: payat.io/dstv/***8.i tried to log on to their self service which was not helpful instaed i later received an sms stating thus Thanks for your DStv payment. We've reconnected your services, but you still need to pay R50. You can check the details on *120*68584#.i honestly feel that multichoice is taking advantage of their customers due to the incompetence from their accounts department. I honestly can not allow to penalised for something i know nothing about.let them solve the incompetence of their accounts department staff and not charge me R50 extra while they took away the service that i already paid for even if its for few hours i had alreasy paid for it
