missing data.. incentive Igig given then removed..

I took out a contract in April 2015. With the smart s I got a 1 gig incentive per month. I also purchased a 250 mg as a fall-back.This was the reason I went with Vodacom and not another competitor. By July I realised I didnt need to have this additional 250 mg and I rang up to cancel it. I confirmed that the smart s and 1gig would continue to run. Unfortunately I realised later that they had stopped both on the same day. With on going verbal complaints I eventually GOT A RESULT 2 0ct 2015. AND i WAS ADVISED THAT THEY WERE RE-INSTATING THE 1GIG. All cool you may think even though I had lost the months in between at least now I would have the data I should have. I realised later that they had only added the 1gig for that month or something.<br> I have subsequently tried going into the centres and using the 08211. Thousands of minutes kept holding and been advised that they can not re-instate they wont give you an email address to followup or another more direct number to use.. No-one wants to take responsibility and I have reams of names but no results.
