Telkom the greediest company ever

Telkom are the biggest ****** my debit was rejected of R11 and now they are charging me R202.70 over a R11 debit And which I did a deposit of R310 two days before they did the debit so which means I should have already been paid up the only reason why I decided to pay them before they did the debit is because with this coronavirus everything is being affected telkom doesn't want to help their customers I tried to get that R 202 rejected they tell me there's no one I can speak to no one can help me I am reach the end they are the biggest ****** ever
