Tried and tried last night (4/10/22) and again most of the morning (4/11/22) to buy tickets. Called Capital 1 (cc company) to see if my card wasn't working and they told me that all day yesterday they were having people calling them as their cards on your site didn't work either.
FINALLY found a phone number for you and called and spoke to Romeo who was simply the best! Finally got my tickets and had a great time speaking to the very helpful gentleman. He deserves 10 gold stars!
