Looking for support for as a disabled business user that can't speak, type fast enough for live chat

[DisableBiz]

Got a shock for the out of contract price increase, want to change to a different plan, but only way that I can find offered is if I can call.  

Is there an email to contact support for billing?  - I struggle to type fast and need to edit messages a lot due to shakes and pressing the wrong keys, making "live chat" hard to use.

Hope for some help.
Cheers.

Hi DisableBiz

If you are unable to call in or use the livechat, I would suggest you see if there is a BT Local Business that covers your area as they will often have a contact email address and can assist with re-signs. You can put your post code in this checker here to find out,
