I replied in the review thread with a point-by-point response to each 4.3(a) factor and asked which app mine is believed to resemble
You've asked what!? Which app of yours? You've said it's your only app.
These days, they let a bot reject your submission a few seconds after they start reviewing it if the category you have chosen is very crowded. They are out of hand. I guess you have to tell them under the App information section how unique your app is, which sounds totally absurd, though, because you have to know how other apps similar to yours work.
