Though you did your original message a disservice. Now we are left wondering how forthcoming, honest and friendly you were with that support staff. I'd also try to cheap out if I'd have to deal with a rude and/or dishonest customer. I'm not saying you were, but it's hard for us to know if you throw things at us like "why should I care?" You need to understand that this causes certain reactions.
I personally don't mind at all that you used AI to make your writing more accessible. To the contrary, I think it's a very suitable use of the tool and I would do the same.
But don't you realize what impression you are conveying to the audience here by being so strongy defensive? To the point of lashing out at bystanders like me? That's exactly what makes people wonder how you interacted with the company that you are so strongly (and likely rightfully) criticising.
To answer your question, by "owning up" I meant admitting to using AI for the text after initially denying it. Again, no judgement on my end for having used it. Apologies if my choice of the term implies a judgement to you. That wasn't my intention.
