Poor Service from Call Centre

My cell number has been locked due to a Vodacom technical issue which ignores the increased call limit set online. I contacted the call centre who were unhelpful in trying to resolve the problem. I was told that a service request has to be logged and the turnaround time is 2 business. As though poor reception and constant dropped calls aren't enough to deal with. I was going to renew my contracts with Vodacom which I have had since 2000 but this will not be happening. Cell C here I come.
