Appalling Service

I have paid my account in full after being handed over to attorneys, I have received my paid up letter from the attorneys and the settlement letter from Vodacom. I am wanting to take out a new contract but I have been told that my account is with the legal dept. I have called the legal dept and have been told by 2 so called team leaders that they have sorted the issue out and that I would get a callback, 2 weeks later my account is still in the legal dept and the status still hasn't been updated. I have been blocked and cant call in because I have called in so much to get this issue sorted out. I would like to be called by someone more senior than a team leader at vodacom because there is a big issue with the level of service they offer. Its pathetic that Vodacom take so long to update a status and my account was paid up 2 months ago. My number is ***
