Vodacom does not care about their clients

I have had it with Vodacom!! As of last month vodacom decided my account was to high and just suspended my line with no notification! After the 4th time this happened because I came to close to my credit limit (That no one from vodacom informed me even existed as I'm a contract client) I found after a bit of investigation I never even reached the limit but the internal system kept on suspending my line causing a lot of frustration and money because when you travel in Africa and your phone does not work because your supplier does what ever they like is no fun at all. I have sent mails to the customer care department spoke to accounts department on several occasions and 082111 that is the most unhelpful bunch of people put together. You can not escalate anything as they block you in every way they can and I even went as far as to stop my debit order to just try and get their attention and every time I get the answer that someone will call me back but I have been waiting for almost a month. VODACOM does not care about their clients and I want to cancel my contract!!! From here I'm also logging this with the ombudsman
