Pathetic Service

I am absolutely FED-UP with your PATHETIC service. Firstly I was called in to upgrade my contract, 3 months prior to my actual upgrade date. I wasn't informed that I will be charged for two handsets for 3 months due to an earlier upgrade which you advised me to do. Beside this issue which I have now simply had to accept. I received my phone on 03/11/2015, I was also billed on 03/11/2015 thus I have now been charged an entire extra months use of a new phone which I only had for less than a day. After three months of explaining my story to hundreds of call centre agents and logging my query umpteenth times I was finally called back and informed with \oh well that's how it works". Now I am stuck with a two year contract having to deal with this kind of service"
