Sorry if this is the wrong board, the domains threads all seem to be about which registrar to pick rather than problems with one, and this is a problem with one.
Some background. I moved one name to BPServ about a month ago because I wanted the domain and the box at the same shop and their VPS side has been fine for me. Registration went through with just an email, paid in Litecoin, thirty dollars for the .com, all straightforward and honestly easier than the mainstream registrar I came from.
On Monday I changed the nameservers in their panel because I moved the site. Panel shows the new ones. Public WHOIS still shows the old ones three days later, and the site is still resolving to the old box. I have raised a ticket and had nothing back.
Is three days normal for them? Or have I done something wrong in the panel that it is not telling me about? Thank you to anyone who takes a look.
