Just an update that I received my money back on 28 June (~150 days after initial refund). From the original $10,000, I received $9917 ($83 for bank fees due to multiple attempts). According to CEX, they attempted to transfer on 1 Feb, 6 March, 31 May, and finally on 7 June which was successful.
No complaints. I am glad I got it back.
