Customer care unable to assist

I recently upgraded my vodacom contract and switched to a smart L package from a top up. My work requires me to have both minutes and data available throughout the month. I get a cellphone allowance.

By the end of October my contact was supposed to change. I received numerous adverti*****ts and messages to this effect. The problem was that none of my data was available from the 1st of November.

After several calls to customer care the problem persisted. Several technical requests were send with names of people and reference numbers that was supposed to contact me an resolve my issue. None of these technical support members phoned me. After each reference the next message appeared stating the request was now resolved. I then dialed again and the customer service department stated that it would be best to go to any vodacom store. The first store I went to was unable to assist as they could not access my account due to unresolved requests.

Today is day five, the process repeats itself every day since the 1 November. What am I supposed to do?
