Waiting for my Deposit

I left the property i was renting in at Richmond Park in an immaculent condition. In fact, the new tenants went out of their way to thank me. I stayed for one year, never missed my rent, left on the 29th of Dec 2025. I would like to think i am one of those human beings that is always considerate of others however , i am not begging for my deposit back. I was told 21days & still nothing , what a disappointment guys, there is very little integrity left in this world sadly.
