DEDUCTING UNUSUAL AMOUNTS FROM MY ACCOUNT

On the 25th August I paid over R1000.00 to NA ********** as I did not pay last month which was R934. Therefore this month it should only be about R700.00 as I was not able to use my phone the whole month. They deducted on 1st Sept R2082.36. This is ridiculous as it should not be this much. No one is willing to assist I even emailed the CEO Shameel Joosub and still have not received any assistance. Service providers are always quick to harass you for money but when you require a refund and want to charge them for the bank charges due to the failed debit orders because of the debit order error their side no one seems to be available.
