Several years ago I used the services of gate.io. After a long break, I decided to use this exchange again. But when I transferred USDT, the exchange blocked the funds and for a month now they have not done anything, they only answer me in a ticket that they are looking into my question. My account was verified, the country, city, email and phone number have not changed. How can this issue be resolved?
You should open a Scam Accusation thread against the exchange but only if you know you have enough proofs to back your statements because you can't blame a service or a website just verbally while not having anything to show. You should have screenshots of your funds that are blocked, maybe your conversations with the support team and their responses to your questions and tickets, and anything else that can serve as proof in this matter.
You should have first checked with the support team before depositing funds if your account is completely okay to be reused since you said you haven't used it for a while and accounts often get temporarily blocked or deactivated when they are not used for some time.
