Upgrade Gone Bad

I am due for an upgrade on both my contracts one is for my iPad and the other is for my LTE Router , my contracts were paid meticulously and up to date with no default , I requested an upgrade on my Ipad Air to a iphone 6 S Plus and me being a dedicated customer expected some immediate service delivery now I am told I have to apply for a new contract which is totally unfair and not realistically logical given my contracts both expire and why cant the iPhone be integrated in my existing contract then I rather cancel all ties with Telkom Mobile if this is the service I receive when I was one of the first customers that marketed their products .
