CONSTANT INCORRECT BILLING

I recently signed up Telkom for Fiber, on my application I submitted I requested a debit order to make life easier and to ensure payments are on time, not knowing although I filled it out on the application, they dont just set up debit orders as per my request so my first payment was apparently late because I was then informed to make a manual payment. I made my manual payment and then received my second invoice when I received this I called to set up a debit order just to be told that it takes 30 days to ''kick-in'' for a debit order to run so for my second payment I must make another manual payment despite the invoice saying it will debit my account which I questioned with the agent they said NO I must make a manual payment and let me add that they was a late payment fee on there due to my first payment being late because like I said there wasn't a debit order on as per APPLICATION REQUEST in the very beginning. I left the late fee charges of R20 and made it with my second manual payment just to see that the they also tried to debit my account?????? Like what the heck, I wouldn't of done all the effort of driving my petrol out to go make a manual payment if they advised me correctly I would've left the money in my account. So i was charges by my bank for R61 which I queried because it is still not my fault and now to top it off for my 3rd invoice I received Telkom is also charging me R211.99 for a service charges for what????? All i see here is I'm being charged and I do not accept these charges because If my application was done correctly none of this would of happened!!!!!!!!!
