Thanks for your first post and welcome to our forums page.
Unfortunately, this isn't something we are able to help you with from here, however, if you speak to the team on 150 / 0345 454 1111 option 1, option 4 then option 5, they will be more than happy to look into this for you and do their best to find a package to suit you.
Any luck on haggling? I got an initial offer to downgrade from £45 (200mb + evening calls), to £37 (100mb + evening calls). But elsewhere like Plusnet and TalkTalk all offering £28 for switching with 65mb + evening calls.
Anyone got a better haggling deal than £37 per month?
