ChatGPT - output is unusable

I have been using ChatGPT for several hours now, and it keeps failing. Either it stops halfway through the output, or what is being output is unusable. So, I try to get in touch with their support, which is completely impossible. Here, I only get a robot that doesn’t even try to help.

I am a paying customer and am currently very dissatisfied. There is a long way to go before AI can be taken seriously!
