I can't access the gpt plus chat that I've been a subscriber to for over a week

I’ve been trying to access the gpt chat service for over a week but I can’t. The message in the screenshot above always appears. I already did the recommended procedures to try to resolve the problem, but it didn’t work. I really need gpt chat and I always use it, strictly complying with its policy with good practices. I don’t do anything that goes against your guidelines. I am a paid user and one of the first to use this fantastic tool since its inception. I urgently need a solution. I understand the overload of the platform, which makes it unstable at times, but apparently that’s not the problem here, since I’ve been without access for many days. Thank you for whatever you can do.
