This is very strange to me because this exchange that you mentioned hold a very high esteem in my heart. I respect them so much as I respect Binance so I would still not want to believe that it is a deliberate action. Everything you have done here is right and I dont see what you need to do again, because you have already contacted the customer support about this situation, and the only thing I would advise is that you keep pressurizing them and also check if they have Instagram account that you can use for further contact.
In as much as we want to help, we might not be able to do so now until probably we are able to actually verify that what you have said is nothing but the truth, so if you can just get us a little proof, then I will be willing to be among people that will retweet it for you.
What kind of screenshots do u need from me to believe me?
