We were with wanadoo (taken over and became orange). The price had increased from £17 a month to £23. I called to cancel the account in order to take up with another company who were offering the same package for £13 a month. Orange immediately offered us a reduction to £12.99 a month PERMENANTLY with no length of contract to be tied to (and we have this in writing). If you're out of the initial contract time the try changing - it generally scares them to death as no-one likes to lose customers.
