Very unhelpful

I have been trying to get my old number back for 2 months now. The number was disconnected (as in stopped using the number due to me getting a contract from work) after I contacted Vodacom get my old number back via customer service they told me this number is available, no one is using it and to visit a branch to activate. I went into Cape Quater where I was told only customer service will be able to connect the number again because the number is out of service. Customer service then advised the number has now been deleted off the system. After that I visited yet another branch - Cape Gate, I was then told the number is deleted but can be reinstated by the head branch Canal Walk. I would love for this to be sorted out, get my number back that I was told is still available and have to deal with this anymore.
