Have not received Deposit Payout

I moved out at Capital Heights in December 2022. I informed Rina and Unike who never responded to any emails. I request for my deposit to be paid out in 21days as per contract but it's two months now and I haven't received any response from Unike who Rina claims that she is the one handling that area of business. The management at Amantle Properties are so unprofessional. Pleas assist me to receive my deposit
