Worse worse worse

At this point I cannot wait for this contract to end this is ridiculous because each and every day its another struggle on top of the other firstly I had to pay for something that was their fault because their system wasn't debiting" the correct amount so according to them I was late 7 months of payment..this month they kept trying to debit almost all the time( not on the agreed dates) tell me why did payments go through for 2 days in a row I paid R495 yesterday and today a debit of R238 went off this morning anyone care to explain i need my refund back
