Unable to make calls or sent text messages

<p>I upgraded my cellphone during the middle of October and as from the 1st of November I am unable to make calls or sent text messages. I visited the branch countless times and was told that they have contacted Vodacom to resolve the problem. I have also contacted Vodacom directly on numerous occassions without any success. I have even visited Vodaworld and spoke to the technicians and was informed that the problem will be attended to and that I have to wait 48 hours. This time has come and gone and am I still unable to make calls or send text messages. I am an attorney and need my cellphone for work. I find this unacceptable. If the problem is not resolved by Thursday afternoon I will return my cellphone to the branch on Friday morning and cancel my contract with immediate effect.</p>
