I accept I may BU here but as I'm going to learn a 4 figure lesson I think I can ask...
I rented a property. It was first property I'd ever rented so I didn't know how it worked exactly. I paid my deposit to the letting agent. I was told it had been protected. There was no check in nor check out. My landlord was resident abroad (somewhere in the Caribbean, Caymans I think) for tax purposes so I never met them.
I was going through a lot of personal issues when I left, police etc were involved. It was a difficult time. I was also working 300 miles away.
With everything going on, it was only once stuff calmed down a few months later that it occurred to me I'd not had my deposit back. Id had no contact with agents so contacted the co who were protecting the deposit. They said as it was more than 3 months from the end of tenancy I was too late, and they didn't hold the deposit it was with the agents. My only recourse was to them.
I contacted the agents. They said they had never held the deposit and id need to contact the landlord. Except as landlord is abroad that's basically impossible, and I cant even take it to small claims because I don't have an address in UK for the landlord!
I know now I should have done something in 3 months. I had so much other crap going on, plus I didn't know there was such a strict time limit. It just seems so unfair I'm now a grand down and have no recourse.
