Cannot provide What I want

My contract with Virgin Mobile expires tomorrow on 24th December. An upgrade agent phoned me two months ago to upgrade but told him I wanted a Samsung S6 or iPhone 6 and was told I will have to wait until there is stock and one will be kept for me and will be phoned. Nobody came back to me and I tried in vain for weeks to get somebody who could help me to upgrade, until the 15th when Jabu took my details and promised to get back to me after he unsuccessfully tried to get me to change to an LG G4. He never came back to me and I have since phoned in 4 times and was told the upgrade was approved on the system but he's done nothing about it, every time an email was sent to him to phone me but it never happened. <br> <br> Today I was phoned by Sam who again tried to force the LG down my throat and when I declined, the Samsung suddenly became unavailable and the phone was cut. I phoned in and even though the system said I was number 1 in the queue I was kept holding for more than 20 minutes. <br> <br> It is clear that Virgin mobile cannot provide what I need and the contract must come to an end when it expires tomorrow.
