Credit limit bar activated

<p>I received a message from Vodacom stating that my credit limit bar has been activated! Since then I can't use any data and can't even dial *100#. I don't even know where this came from. I have phoned several times now and they cannot see the reason for this, the call centre just says everything is fine on their side and my account is not in arrears as it gets paid by a debit order! they advised that a technician will contact me! I cannot believe that you pay for a service and then you cannot use it! I have more than 3gb of Data on my tablet and I cannot use it! I will definitley cancel my contract with Vodacom!</p>
