Excessive unknown Debit Order

<p>A debit order was taken off my account for the amount of R803.51 and Cell C are unable to tell my why apart from its an open line! I have 2 contracts both on top up and blocked from accessing further data & expense when they run out. I have spend nearly 20 minutes on hold for the 'open line' department to deem my worthy of answering my call and given up. There is apparantly no other way to get assistance. I do not have the time, nor money to waste phoning incompetant call centres who cannot answer their phones!!! How does one sort this matter out or get clarity as to WHY this happened?! If i reverse my debit order, they will probably freeze the account... so stuck between a rock and a hard place and NOT IMPRESSED!</p> <p> </p> <p> </p>
