Need to change installation date

[#1]

I need to change the installation date that we booked but I can't find anywhere on the site to do that. We have an engineer due round next Wednesday and we are now not getting the keys until that day so might not be there when they arrive.

Thanks for your post @ScottB 

We'd need to delay the appointment from our side as it isn't currently possible to change it online. 

If you can PM me 2 or 3 dates when you'd be available for a visit after the one it's currently booked for I'll be happy to delay it (There may be another week or two wait if we reschedule the appointment)

I'm not in the office tomorrow and I'm about to log off in about 5 minutes but I can pick this back up on Friday if you PM me.
