Thanks ladies,
The letting agent company has been pretty crap about things to be honest. Which isn't exactly news to anyone, I'm sure.
I'd called about it, but she said she'd have to go to the actual file and see what she could do since NONE of the documents were on my login. And she couldn't promise I'd have anything today.
Heck, only the last two payments we've made to the company are even showing up on my online account. They are absolutely pants.
Luckily, even though I wasn't sent anything, my husband was.
So I have been able to send it off with a electronically signed copy of our current lease. We all signed it electronically, so that had better work.
Or I will be very sad and heading back to the US in however many weeks.
And it still cost me less than 10GBP to send Guaranteed Delivery.
This one has been a bit of an ordeal.
