Trying to cancel Vodacom Contracts is a almost impossible - DO NOT TAKE A CONTRACT WITH VODACOM

I have cancelled 2 of my vodacom contracts twice now and still being billed / invoiced. The second time I called to cancel I was told that my account would not be debited in February yet is was. When I called in I was reassured that that was the last debit order only to receive invoices yesterday due for end March. When trying to cancel my contracts prior to calling in a few weeks ago I walked into a Vodacom store. What a nightmare, staff sitting on a chair eating, others chatting to each other only to be told that they can't cancel me in store, I had to call in, which I've done TWICE!! Yet to be invoiced again. I've stopped my debit order with my bank. What utterly pathetic service!
