Telkom WiFi contracts ****

We had a WiFi Contract with Telkom since 2020 if not mistaken then in 2022 we upgraded to the unlimited plan paying R600 a month everything was fine until in October 2023 they started to debit more than R1000 then again in November when my mother went to enquire they said we have daily subscriptions and there is nothing they can do, then my mom asked the guy at Telkom Secunda to please cancel the subscriptions the guy said he's cancelled them but still in December 2023 they debited more than R1000 then my mother disputed it , they then cut off our WiFi and went to the branch again and she was then helped by a lady , the lady said no the subscriptions are still on , so they called the head office and gave us a case number and said they admit that their employee was wrong and followed wrong steps on cancelling it, then they said they have cancelled it , but they continued to debit again even though they cut the WiFi then my mom went to cancel the entire contract, and has been going to Telkom Secunda since 2023 December and the entire 2023 they kept saying they are in the wrong they will refund her every time the head office would say in 14 days they'll refund it's been months and months,all a sudden my mom owes them over R10 000 even though the contract was closed .

My mom has all the account details and all the case numbers from the branch and head office. If any one is willing to help us, to resolve this thing please do reach out your help will highly appreciated.
