Vodacom made me pay then deleted my number

I paid for my contract cash inside Vodacom Kolonade. A month later I received a statement saying I still owed them for the previous month. I queried this, and natrually did not pay until Vodacom Kolonade gave me clarity on where my money went to. After two month going into the Vodacom Kolonade store who kept telling me there is nothing they can do and I should go to Voda World in Midrand to get it sorted. Eventually we discovered that the Vodacom Kolonade branch had allocated the money to the wrong account. They then reallocated the money to the correct account at this point my sim card had already been suspended. By the time we had sorted it all out my number was deleted off the network. And I was told to pay the balance of the contract and they would reissue my number. I did that, once paid they then told me that there is nothing they can do to get my number back. I went to the Vodacom Kolonade store for assistance as they had better background on the issue they had created. The staff literally all kept telling me they are coming back and went into the office and never came out. The store Manager told me to my face that he does not deal with that and would go to the office and call the person that does. I sat 30 minutes waiting for someone. No one came out or back to me, until I eventually left. I paid for a service in full that I did not get due to a mistake that was not mine. A number is more than just that. Its is an identity I have had for 10 years. all my documents have that number on it, who knows the opportunities I've missed because of this. What pains me is, no one wants to take responsibility for this and I am left numberless with no explanation or recourse
