Poor service on ADSL line

My ADSL wifi has been switched on and off since March 2019 when I asked for a relocation of my ADSL line Telkom created a new line which I said I didn't want I told them 2 cancel the one line ,my bill is double the amount since then because Telkom has two ADSL lines active . Telkom is debiting from my account more and I have no WiFi but its paid for . Hence I have been calling in and disputing it however the case gets thrown out and when I call in again the agent make it look like its my fault ,this has been going on long enough . I want to be refunded my money from Telkom . And I only want one ADSL line for WIFI , Telkom can see they mistake why can't they correct it . This is urgent . Need feedback A.S.A.P This is pathetic service from Telkoms side I am very disappointed in this type of service from them.
