Telkom *******

I am being billed R351.7 for a Contract that is for R149.00 all because I had switched banking details for unforseen circumstances my debit switch did not happen on time, 4 days later I took it upon myself to do a manual payment and upon enquiring with Telkom regarding an additional R200 +, I am advised that it is because they did not find money in my previous account, this is a *******.
