Overcharged

My debit order failed on the 27th of July, due to insufficient funds, resulting in my DSTV services being suspended 2 weeks later. Not sure the exact date when my DSTV was suspended, but was around the 11th or 12th of August up until now. <br> <br> According to Multichoice, my outstanding amount that will be debited today 27/08/2015 is R595,30 (for 2 weeks of use), then i need to pay another full subscription to be connected again.<br> <br> R595,30 seems like a very high amount to be paid for such a short space of time that my DSTV was active for the month of August. Please can this be investigated.<br> <br>
