Pathetic service

I received my invoice for my router which is R139/month. Last month I paid 2 months subscription. The invoice came stating I should pay R349.

I called their customer care and Dipuo was rude and didn't want to listen to what I was saying. I called them in August to stop them from debiting my account but was told they attempted. How do you attempt after manual payment was done? Telkom has turned into a day care centre
