Play Million Casino - Payment of $2720 delayed over 3 weeks

A little back story, I've played on Playmillion for many years now (close to 5, on and off). I am fully verified (many times now) and my withdrawals are usually always processed in a timely manner however I recently found myself in a frustrating situation where support is totally not helping me.

On October 31st I made a withdrawal using bank wire, as usual. Except, to this date, I have not received it and the reason support is giving me is: their partner bank is not getting back to them. I've asked for a swift number so that I may track it myself and to investigate with my own bank, but they are incapable of providing me this. What makes it more annoying, my withdrawal done a few days later (November 5th, was received within 2 days).

I don't know what to do anymore and am unfamiliar with the complaint process regarding the MGA.
