Unauthorized billing amount

Since I lodged a complaint, on the 23rd June 2020 no one made efforts to contact me in order to resolve my dispute. I visited Woodlands outlet again on Friday 10th July and requested to see the site manager. All he could tell was they are working on the dispute. I'm losing money and a receiving a very bad service from Telkom. Have visited the site 5 times since the inception of the lockdown which poses more health risk.
