Telkom bad service and provider

I have payed my account on 22 February 2020 in full . They however only reconnected my services on the 25th were my WiFi only worked for 3 hours I reported a fault and waited for them to respond . They only arrived on 27th at 15h45 were I was told you have a problem with your password and have to go in to one of the branches to be reset my password on ADSL for it to work. I went to they Branch today on 29th were the ADSL was tested and it was working 100% with out changing the password. I arrived at home very joyful to have my WiFi working. Instead it was not working again I reported the fault again after being on the phone for 45min just to be told that there is something wrong with my line. How do I go forward with Telkom’s bad service and excuses. I have been paying a services that I can’t even use
