Good luck, despite you thinking so it's not as simple as clicking your fingers & things will start working, there's obviously issues which need to be resolved. I'd also suggest editing your post to remove your personal details.
FWIW, I'd give BT a call & be polite instead of just demanding a connection tomorrow & request some form of 4g connection in the meantime & what rights do you have to 3 months of free bills due to an issue? You'll get the automatic compensation for delayed connection/missed engineer visits, there's absolutely no need to be demanding 3 months refund too
