Did they give you any reason for the deletion of the ticket you've sent to them? is that ticket you've made is the "chat with us" feature that you can see below their page?
Contact them through telegram.
https://t.me/OKExOfficial_EnglishJust be careful of scammers and imitators, contact the actual support on that group.
No reason for delete the second ticket. The first of them continues open, but no replies since 14th february at 7.30 AM.
If they have a problem with XTZ node, I'm just asking for a response like:
"hey bro, sorry, our XTZ node needs and update/resync, wait for 48-72h and your deposit will be credited".
This would be to get angry but at least I have an honest answer and I no longer worry.
But no, they decided the silence as a response, and only when I posted this and make some noise on twitter, they suspended the XTZ deposits:
We are sorry, deposit of XTZ is temporarily paused due to node upgrade. Please try again later.
Does it seem serious to you that I have to do this to be heard?
