Vodacom completely useless and totally unprofessional

Once again Vodacom has proven to be absolutely useless!!! I changed my bank account last month and phoned them (holding the line for almost half an hour because they are always busy... Maybe because everybody has issues with them...) I spoke to a consultant who said that he had changed my banking details. I also asked for my debit order to be moved from the 7th to the 1st of the month. The consultant assured me that he had. So this month, on the 9th nothing had gone off from either account. Turns out they cancelled my debit order in stead of updating my details. And no sign of my new bank account details. The consultant asked me if I wanted to speak to another department. I said yes and asked to be put through. Then she says I can't speak to them, she has to speak to them. MAKE UP YOUR FRICKEN MIND!!! Held the line for an eternity again, waiting for an answer. Still no answer. To top it all off this consultant was highly unprofessional. It sounded like it was her first day and she answered, while telling someone something to the effect of: "oh what a week..." I spoke to Busi who said I will only be debited next month. All hell will break loose if I am debit for double the money...
