Deposit refund

The guy who is (Garth) responsible of Rivendell Property is very ignorant when it comes to tenants issues, I have been struggling to get my deposit money back after moving out of the rented apartment. I moved out of the apartment on the 25th of Mar'20 before the lockdown however I can't get my deposit money refunded. I handed the keys back after making numerous calls asking them to meet up with me so that we could do the exit inspection. I have done this beginning of May 2020 but can't get my deposit back and the guy is not responding to my calls. I am now ready to take legal action.
