Dissatisfied with multiple group

Hi I been badly treated by Multichoice choice group, on the 26/03/2023 I phoned their call centre and spoke to their call agent by the of Mbalenhle Xolo who told me that she sees on her side that I qualify for a discount amount of R410:00 for the coming two years. I moved from a normal DSTV compact extra view to a price lock plan. I became alarmed when I checked my account balance which stated that I owed 860:43. So today morning the 07-04-2023 my viewing connection had been disconnected, I even received a confirmation email that my services are active. I just phone them a short while ago and they say my matter is being investigated mean while I'm without the viewing connection. Please assist in this regard. Multichoice reaspes off its customers.
