Showmax error 402

Constantly receiving " ERROR 402 - payment required " My payment is linked to my DSTV account and paid via debit order timeously monthly. After much persistence on the first time I got the error, I logged onto the Showmax live chat - I was informed that the average waiting time was 128min for assistance. Why in the world would you have a Live Chat and have provide such poor service. Eventually assisted the NEXT day and the ERROR was resolved. Only for the very same ERROR to appear again 7 days later. Having the very same issues with the Live Chat, No assistance, No replies for hours. DO we have to go through this process every 7 days. So frustrating.
