Duplicate deductions

Vodacom tried to take of a debit order from my account. Instead of R389, they took R933.<br> I did not have the amount in my account because I did not budget for it.<br> now they suspended my account with no notification, and its not even me that made the mistake.<br> I called last week and Vodacom did say that they made a mistake. today they cut my services.<br> when I call today they only tell me that I must make the correct payment before they can activate it.<br> but if they deducted the correct amount this would not have had happened.<br> now they tell me that it counts against my name. but Vodacom made the error.<br> previously if my debit order did not go through, Vodacom will phone and make an arrangement for a deduction the next month. But not this time, now that its there fault my account gets cut.
