Vodacom debt review

I have been a client at Vodacom for 3 years now, I have a contract with them, unfortunately due to circumstances I am now under debt review. However my Vodacom contract is not part of my debt review, I have been paying Vodacom every Month. I am now due for an upgrade and as I went to do the upgrade (Phone of choice, because I know what I can afford and what not. ) I would not be applying for a phone if I know I can't afford the installment. So I went to do the upgrade and they refused to to the upgrade due to me being on debt review, but as mentioned above the Vodacom Contract is not part of my debt review. The more I tried to tell the lady that the contract is not part of my debt review the more she shook her head at me saying no we can't do it.
