Vodacom - customer service - what's that?

I have been trying for months to cancel a Vodacom account. Call to change my bank details, they confirm, zap loads of money off my old account after receiving an sms to confirm new bank details. When trying to cancel a contract you have to go from one department to the next, speak to loads of people who don't listen to you. This is so frustrating and I know I am not the only one. When I asked to speak to a team leader I was told it is the bus strike and not sure what time she would be in!!!! Just checked my bank account and the cancelled fee went off again. So how long am I going to have to spend on the phone to get them to refund my monies. The person I spoke to probably did not complete the transaction. Frustration and dissatisfaction with a service provider. Vodacom - you don't know how much emotional stress you impose on your clients. Not sure how many of your 55 million customers are happy ones!!!!
