Booked through Costco

Has anyone ever booked through Costco? I have a odd scenario that I’ll definitely be calling them tomorrow am when they open. So I attempted to book my cruise and the website spun saying processing and continue to spin for awhile, the website then like blinked and continued to spin before it just stopped. I have no confirmation, no email and I checked my credit card and I have 2 pending charges (should only be one) is this normal!? I’m panicking a bit since I have 2 pending charges without any receipts or confirmations
