Telkom Service pathetic! ***********!

I have moved onto a Fibre product about 3 months ago and went to a Telkom Centre to give notice to cancel my ADSL service. After the 30 days I realized to my dismay that my entire Telkom service including my landline had been cancelled. I battled for about 10 days to get that mistake corrected. And since then, another 2 months down the line I have been battling to just downgrade my service to landline only ie cancel the ADSL. It is still on my bill and as part of my services! I sit on the line for about 40 minutes at a time and then I abort the call. When I check on their app with my reference number it says awaiting stock from the warehouse???? What stock????? I am paying R150 per month for nothing and I just cannot get them to fix this??? Is there anyone out there that can help??? Telkom knows it has the monopoly on fixed lines so they don’t care about their service at all!!!!
