Billed for disconnected services - no one can explain why.

We have had dstv premium for more than 13 years, due to covid and the lock down, we had to downgrade to dstv access. We had asked to disconnect extra view and were told it was disconnected, yet they continued to bill for it. When I finally picked this up and queried it, no one could explain what was going on, I spent hours on the phone, most times running out of airtime, and they are the most unhelpful bunch of people! I was told I will receive feedback from someone regarding the query that was escalated, but nothing. The service is pathetic, I'm absolutely disappointed!
