I also read the review text and his ad's narrative. We know Rentmen will remove negative reviews at the advertiser's request, so he could have had at least one of them removed. Instead, he chose to leave them up and explain the issue as he sees it. To me, that lends a bit more credence to his side than if he had simply had the review/reviews removed.
Re: video "quality." This could mean different things such as a grainy, low-res, out of focus video (which would run counter to the claim that his boundaries were not respected) or the content is not what the client was expecting. Using a silly example, if the customer wants a vid of him fucking a roll of Cottonelle toilet paper, he says "hey man, I don't do toilet paper. Kleenex tissues with lotion or nothing," the client agrees and then doesn't like the content (i.e. the content's quality) it is plausible that he did not respect the escort's/content creator's boundaries. (No TP rolls, just Kleenex with lotion) As for the no-show, it is possible he showed up and the client was pissed 'cuz he wanted Cottonelle play, Not probable, but possible.
Before the masses grab their pitchforks, leash their hungry/mean dogs, and head for Phoenix, here's a real-life example.
There's a guy in town who advertised as being straight, would only do muscle worship, and/or go on dates/events, I happen to know him, hired him, and reviewed him and also know that he was dead-on serious about his limits. A guy reached out to me asking about the provider's services. Before I had a chance to answer, the guy had hired him and was upset because the provider wouldn't let the guy suck his dick. His comment to me was "I didn't realize he was serious when he told me he was straight and only got into muscle worship."

So...it is somewhat probable that something similar occurred with the reviewer who claimed he didn't show when, in fact, the provider did show up but the experience was not to the client's liking because his expectations ran counter to what was discussed.
Pet the attack dogs for me, would you?
