I moved out of my property two weeks ago and no one can get hold of the LL to get my deposit back.

She will be in contact with the agency eventually because they got a new tenant in.

In the mean time the agency have emailed twice, sent texts and tried to call her phone several times.
I desperately need my deposit back. Even when she finally does sign it back, it takes the agency 5 days to release it (why?!)
So it's going to be at least 3 weeks by the time I get it and that's if she gets back to the agency today.
Which she hasn't so far.

Apparently she doesn't have a legal time limit. I need to start a dispute.

What the hell?

There is no “they”. You are meant to be given a number and you as a tenant can check exactly what type of scheme it is. It’s not really the estate agent’s job. You are given the certificate number when the deposit is protected and you can take action with the scheme, citing that number.

any update OP?
