Bad service

I still fail to understand why no one at Vodacom could ever just pick up a phone and explain to me that I can't pay via eft and that they HAVE to do a debit order. In more than a year of struggle with them. I was promised that a manager from their accounts department will phone. Its been more than a week and I am still waiting. Like I knew I would! Can't wait for my contract to end in July!!! Counting down the months. One call to me would have had my new bank details and everything. But NO! Lets deduct a suspended account for over a year!!!!!!
