I'm afraid everything that you read on this website is true. I've dealt with a great many dodgy estate agents in my time, but Felicity J Lord are without doubt the worst.
They are pushy, rude, arrogant, unsympathetic and entirely unhelpful. Fortunately, it wasn't necessary to rent with them, as most other estate agents weren't nearly as angry, demanding or overbearing.
From the start, their emphasis was on overwhelming pressurization and they made ridiculous demands, some of which were backed up by claims we since discovered were entirely untrue.
I believe the technical term for this is "lying".
