Vodacom Customer Service worst ever

Worsr client service ever. I was phoned for an upgrade, and they got the date wrong. Suddenly my account is double where I was supposed to save R3. After one hell of a struggle to speak to a person, not a robot Mondo sends me an sms to say the upgrade was cancelled. Only to find 3 day ls later another upgrade is loaded and my account has trippled. I cannot get a hold of upgrades and customer services is ignoring my emails. All their communication is automated waisting my time to try and rectify their fault.
