Olymp Trade — Deposit not credited to olymp trade account nor refunded back to bank account yet.

I had made a deposit of Rupees 24340 through UPI QR on 1st December 2022 but the amount was neither credited to my olymp trade account nor it got refunded yet to my bank account. I made a complaint through mail to olymp trade and they had given a deadline of 30 days from the day of deposit to get refund the amount to my bank account but yet the amount is not refunded, its been 40 days now. They keep on telling that they are investigating but they are doiing nothing even after i had shared my bank statement they asked from the date of deposit till 9th janaury 2023 but still my amount is not refunded.
