Installation tomorrow will not happen if BT dont get my details correct.

This is for any staff member of BT. I am supposed to have my BB installed tomorrow and land line moved to the cloud.

So far BT have got my products wrong, my price wrong and my address wrong. I'm not sure there is anything left to get wrong?

I have phoned multiple times in the last few weeks and keep getting passed around or hung up on.  BT keep promising me I will get an email confirming the correct prices etc. This still hasnt happened and my install time is less than 24hrs away.
I have had to resort to signing up to a forum as I am having no luck with your call center. 

Someone needs to contact me immediately to rectify this or I will be sending your engineer away when he arrives. 
You have my details. I await your call.
