Cancel the freakin debit order Vodacom!!!

Vodacom is probably the worst network provider. I paid off my contract in March but I still find myself having to call my bank for reversals. It's funny how they keep saying they shouldn't be debiting my account but end up doing so anyway. I'm so tired of calling in for the same thing. I don't owe you Vodacom!!! I wouldn't recommend anyone to get a cellphone contract with this company or even choose them as their network provider. It's sad that no one else gives better service but I'm definitely going to move somewhere else.
