Frustrated

Vodacom still have't responded from my second complaint. I have been to vodacom Hillcrest today and the guy told me that IT department should retrieve my number because nobody is using my number it it still available. The guy that phoned me on my first review said it is impossable to get my number back and I cannot accept that I am very sure there is something they can do to retrieve my number. Someone is not doing the job properly. I need my number back and I will keep on expising them if they keep doing this nonsense to me. NO ONE HAS BEEN GIVEN MY NUMBER So it is still available.
