Tell them you're leaving, they'll do anything to make you stay. This applies to all companies and phone/mobile companies too.
Not quite, in the case of mobile phone companies.
My 2 year Orange contract came up for renewal last month (and I've been with Orange for about 5 years). I was quite happy to stay with them, but wanted to upgrade my phone. Best they could do was £50 for the new handset, and a monthly plan that was £2 dearer than I could get with O2, who were offering the handset I wanted for nuffin (and the same limitless calls/texts/2G a month). I told them this, they said they couldn't match it.
See ya then.
