No Service for contract cancellation from outside RSA

I have been trying to cancel my Vodacom Contract. I am not in RSA and it is impossible to call any number from outside RSA +2***7 for cancellations do not work and any Customers services requests only reply with call ***. USELESS!! Otherwise you are send to Tobi and does Nothing for you. When calling +*** when you press Cancellations, calls are cut-off. What a Frustration!!! The e-mails do not work either and you can not find an e-mail address to send the requests to.
