This happened to me in 2019. I went into escrow and they didn't give me the offer for about 5 days. When I finally got it, it was lower than it should have been. It rubbed me the wrong way and I bailed out of the deal.
How did you bail without losing your deposit? I would have thought if you were the highest bidder you'd either be on the hook for the full purchase or lose your deposit.
If the escalation was fraudulent then you can bail.
