Telkom bad service

I am on telkom smart internet deal which i pay R140 on the 1st of every month via debit order. On the 2nd of January I got a message saying my payment could not go through. I immediately paid using the Telkom pay now service which is available on the Telkom website. About 7days later, my account was debited with the same amount which I already paid on the 2nd of January. I called to find out what was going on, the consultants told me the other R140 would then be used as payment for my january invoice. Indeed my account was not debited on the 1st, great. But today I log on to my telkom account to find out my sim usage, I immediately notice an extra R202 on my next billing for payment rejection. Firstly, thats not what we agreed on when I signed up. Secondly I will not be bul**** for trying to protect myself. I am using FNB and when I realised that my card was missing I immediately moved all the money to my savings account, because whoever had my card could easily spend my money with the fnb tap service. And lastly what gives you the right to charge me for payment rejection, why am I not charging you for debiting my account when I had already made a payment(the money could have been for something else, or the bank would have charged me again if you found nothing in the account)
