DSTV disconnecting services even when payment was made

So tired of Multichoice (dstv) and their payment systems, I have their customer for many years now. Every month I do an eft payment to them. This month I have been cut off 3 times and their system says I'm in arrears. I have called their call centre and they requested proof of payment and my bank statement, which I have provided. So in the first 2 instances they would resume the services and 2 days later I get the same message that I'm in arrears. I have wasted a lot of my airtime and time having to call their call centre. This issue has happened again and I am tired of calling them
