My contract with O2 is up next week and i want to change my contract without much change in my bill. I'm currently paying £15 a month for 100 anytime minutes and 500 texts but would prefer something like 150 minutes and about 300 texts. Will O2 agree with this or tell me that it will cost more? I dont think that's an unreasonable offer myself. They'd better give me the silver K800i for free too or i will be threatening them with cancellation!
