Data not assigned to number and it takes forever to resolve a simple issue

i wanted to cancel my contract as the term was up, but Vodacom convinced me they can give me a better offer, which is what i signed up for, and now a month later, i did not receive the carried over data from the previous month, and i also did not receive the new data promised to me, so i am sitting with a phone and no data, a call was logged and escalated to them but more than a week later, they still have no update for me, all i get is that it can take up to 14 working days to resolve, so my question is what must i do until then as i have no data on my account, and there is no way i am going to buy more as you owe me a lot of data any way, and it only carries over by a month, so my last months carried over data will expire in the upcoming weeks any way, which is not fare since you did not give it to me as yet, and when i do o receive it, if i even do, it will be for a week or 2 and then expire, so i will actually loose out, this is not the service i signed up for from Vodacom, this has to be resolved asap as i cannot wait any longer.
