Billing Nightmare

It’s been 8 days now since I’ve contacted DSTV for answers but with no luck. On the 23rd my balance showed “R847” , next day it had changed to R1453.67, as to where this amount comes from since I’m on Compact plus I have no idea. Contacted dstv via messenger and they “escalated “ the issue; after three follow ups I still didn’t have answers to why I was billed that much. Called the call centre and I was told there was an error in billing and my issue will be escalated again so they can display the correct amount (I was told this will be done in an hour) till today I am still waiting. Dstv should just stop with these stupid rewards if we’re gonna be dealing with billing nightmares because of these “free upgrades”
