My Gate.io Account Locked -Unable to Sell

I started with an issue of not being able to sell the products I wanted on Gate.io. While communicating with the support team, who promised to provide a solution, I lost access to my account. Your exchange platform doesn’t even have live support available. What kind of management approach is this for an exchange?
Please remember that these matters cannot be brushed aside so easily. You might think "nothing will happen," but a lot can happen. I forgot my password, created a new one, and when I tried to log in, it said the password was incorrect.
I urgently need assistance in resolving these issues and regaining access to my account. Thank you!
