Hi Kinks123,
I used to be on an Orange contract and the coverage was awful. I could not use my phone in the house and had to go up out of our road to get any signal for texts and calls which was frustrating. I called Orange on numerous occasions to complain and never really got an answer except one of the masts was down. This went on for some time and I gave up in the end and terminated at the end of my contract with them. I beleive in contracts if you are in one with them that one part stipulates if they cannot provide coverage or services then termination without charges could be an option.
I am now with Vodafone and very happy. Excellent coverage everywhere I have been. I would recommend them.
Hope you can get things sorted.
