Hi,
I’ve experienced similar problems with getting through to the maintenance department to get a long outstanding issue resolved… https://www.leaseholdersforum.org.uk/Discussion-Board/discussion-post/window-repair/
Leaseholder services have finally realised they have a responsibility to fix the window, so now I too just have to battle with getting through on the phone line to make an appointment!
By the way I would make sure you check that the fob works when you get it, as I was sent a fob that didn’t & a couple of replacement ones that also didn’t work. It took months getting a working fob as in Camden Council’s wisdom they have contracted out their key fob service to a company that resides outside of London…
Oh the joys of being a Camden Council Leaseholder
