Hi Keith,
We're using ours, I'm afraid; if you haven't had any success from fellow residents, keep bugging Circle Anglia...
Send them a daily/weekly email asking for an update, and I guess they'll get the message that you won't let the problem be ignored.
Regards.
P.s. Make sure you get get good locks - it's worth spending the extra £50-£100 as there have been thefts and attempted thefts over the past year.
