A password I never set is blocking me from accessing my money. Instead of resetting it, gate.io said "fuck you". Not "send your ID here for verification", they said "fuck you, we are not doing anything."
Do not put your money into gate.io unless you want to get robbed.
I have never been a fan of Gate exchange from day 1, I had my verification rejected couple of times and I just abandoned them and never looked back again but your situation isn't clear, if you can share a screenshot, people can explain better about the situation. Another question is what do you mean by reseting password? Did you send a forgot password and didn't receive notifications on your email, if you do, you will definitely get an email notification.
What if you use the wrong website? Have you thought about been on the wrong website probably a clone website where you must have submitted your details and when yiu try to reset your password, it's programmed to return an f word, I'm very sure that definitely wouldn't be gate exchange, even if you offended them or probably has done something that violate their terms and conditions, you wouldn't be getting that reply again. So check again, I mean the real website.
