DSTV (Multichoice) Netflix subscription which was not signed up for.

I have my own basic Netflix subscription for which I pay R99.00 per month. After my husband changed our DSTV option to "Price Lock", I noticed that DSTV started charging us R199.00 in January and February 2025 for a Netflix subscription. We did not sign up for this. After many calls to team members, I was assured that we would be refunded for R398.00 on our May statement. This has not happened. After contacting Netflix I was told that they only had my private subscription of R99.00 for the basic option which I am paying directly to them. They were unable to trace any payments via DSTV for the R398.00! What has happened to my money? I spoke to another team member this morning but she kept me on hold for 45 minutes. I unfortunately had to end the call as my air time had run out. Nobody has returned my call yet. How do I get my money refunded? Please help! My customer number is ***
