Vodacom Incompetance

Our contract in my husbands name, he contacted them to give me authorisation on his behalf so I could deal with it. They phoned and confirmed. I contacted them today to sort out a cancellation, I was told they need to speak to him. I politely explained that I had authorisation. He repeated that they need to speak to him. I said ok, phone him, he said they cant make phone calls. I asked to speak to the Supervisor and was told the Supervisor doesn't come to the phone, I repeated my request 8 times. He hung up on me. I am disgusted with the service or rather lack if service and incompetence that Vodacom has given me. It's amazing how when Vodacom wants you to renew or buy something everyone can phone you, but when you have a query no one is available. I will be cancelling all 4 of our contracts and look for more professional and efficient service from a different provider.
