Telkom adsl/wifi poor customer service

I have been a Telkom ADSL customer for close to 13 years. The last few months my ADSL package has gone up by about 30%. Since 30 November 2022 I have been trying to change/upgrade my ADSL package and have been unable to do so. I have been dealing with Telkom Table View branch, Cape Town, Western Cape, branch manager name: Nasief Kahaar.
