No response from Vodacom

<p>I have been trying for months to cancel my contract with Vodacom as I have relocated to Europe. There is no working number to call Vodacom from abroad. When dailing the number on their website you get a message that the number is not in use. I have therefore emailed several times without success. I just dont get any response from them. I have even asked family in SA to phone them on my behalf to get them to mail me a premature cancellation quote; they promise the family that they will do that, but nothing ever happens after that. What more can I do to get a response from Vodacom????</p>
