change of service

I requested a change of service from Virgin to Vodacom in January 2015. This was done at the Musgrave store. Despite several visits to the store my number remained inactive. I was then referred on to the Vodacom Service Centre in Gateway. Seven (7) visits later I still do not have an activated number. I have been told it is with the technical department, then I was told that its 'gone to head office' and that 'you will be contacted'. That was 2 months ago and still nothing.
