useless service

my contract ended in December and I have been trying to get my account changed to Pay as you go.<br> but I'm not getting anywhere.<br> <br> I went into the store and filled out the form 4 months ago<br> but the guy who helped me was leaving so didn't submit my request.<br> <br> I went back in January and the new guy did it for me and marked it as urgent.<br> said someone would phone me with in two weeks but nothing.<br> <br> I phoned to try and sort it out but was told that because I am reapplying it will take another 20 days from the time of the call.<br> <br> at this rate another month would have gone by before this gets sorted out!!!<br> And I've finished paying for the phone already, but still getting billed for it.<br> <br> Would someone please call me to sort this out!!
