Vodacom being a disappointment as usual

I contacted Vodacom in June to change my number. I was told I had to migrate to another contract. I agreed to it and then at the end of June no migration occurred. I was told after weeks of trying to get assistance it would be done end July and then I can change my number. It seems now that the migration has gone through. So I call the call centre for my new number only to be told it can't be done unless I buy a new contract. And that Vodacom does not offer a service like that at all. I want assistance with this matter right now! No stupid emails, text messages or dumb auto replies on hello peter. If I do not get a call in 48 hours I am taking this further. You have made a verbal agreement on the phone which makes it legally binding. I am completely unhappy and just so disappointed with the lack of service.
