Just submitted a TX a few hours ago and still no chips from chipmixer. Big amount, concerned about an exit scam here. I have emailed support but just want to make other members aware to use this site with caution.
tldr support should get back to you about your email within 4 days, check you've provided something identifiable (eg your deposit address).
There is a bug with the site where it sometimes doesn't credit straight away - I think it has to be manually fixed.
They used to pay around 1.5btc a week on their signature campaign so it'd make little sense for them to exit scam on such an amount.
If the address changed, there's potential you used a scam link too could you go through your browsing history and ensure the site was definitely their official onion/com domain and check you don't have any add ons on your side that have permissions to change what a website displays.
If neither of the two are the case chipmixer are going to be able to see that funds have been left unclaimed from a certain deposit address and will make them available to you. Just wait by as support can sometimes take up to 3-4 days to reply.
