Unfair upgrade deals

I'm due for an upgrade, I went to the store and selected the deal and phone I wanted. No stock. Went back next day. Only to be told that the deal no longer exists and I will have to pay R270 more for the same deal! After ten years as a customer, I will be ending my contract within two months unless they can sort this out. It's ridiculous that I can't get the same deal as the person I live with (who upgraded two days before I did)! It was their fault to begin with and now I can't get the phone I need on the contract I want! <br> <br> Please contact me. I do not think you want to lose a loyal, paying customer for two more years just because of one error.
