Incompetence

I have only been with Vodacom for 2 months and my experience with your stuff is disappointing. You rendomly debit my account on a day we never agreed on even though this month premium had already been paid in full. The amount that you debited was for an apparent unpaid debit order fee on a month to month contract which doesn't make sense as I can't even opt out of the debit order option . Which I made a payment using an alternative method. Then u decided to debit your penalty fee rendomly as today is not my salary date noh my debit order date. The payment for this month was made on the 21st already. Please reverse your penalty as your random debit as attracted a penalty from my bank as I didn't cater for it.
