Unfairly disconnected my services

Tell me how is my account being suspended because they claim I have a credit of R3000 that I need to settle, when I have NEVER! bought airtime on credit.

I phoned in and spoke to a lady that went through my statement and confirmed that they made a mistake, they mistakenly calculated the airtime that I bought from my bank app and thought I was buying on Telkom credit. LIKE really? its a week and I'm still not re-connected. my case number ***5

They will have to reimburse me for days I couldn't use the services I PAID FOR.
