A bit of clarification.
We, as in ChangeNOW, had some issues with BTC deposit, and that took a while but it was fixed. We informed our customers via Telegram group https://t.me/changeNOW_chat as we do for every single change.

Your deposit of 0.2906 XMR was made 30.05.2022, 17:48:54 and your exchange was completed 30.05.2022, 19:34:51. That's less than 2 hours, and the delay was caused by BTC deposit issues.

Let me know if you have more questions, I would be happy to help and answer.
