Telkom do as they like........

I wrote several mails to Telkom Mobile to make arrangements for payment of my account. The said they are escalating it. I received my Account and the due dat was shown on the account as 01 June 2020 which I would pay, They on the other hand put through a debit order at my bank and now I lost my last money for this month as i had to pay penalties. They also suspended my line immediately after i loaded Data so a loss again...... This is not something new from Telkom and definitely my last deal with them......they are sharks..............
