SeatGeek locked me into final sale tickets totaling $3,800 after their site glitched Internet

After numerous other bugs encountered during my purchasing process (the queue progress not visible, seats not loading, getting stuck in a "robot verification" check...) I finally selected two seats for a show. I didn't get any indication that anything was wrong or different, and of course, the nature of the purchase encourages rushed transactions.

I recall double-checking the confirmation screen, and since everything looked good, I continued. Once the purchase concluded, I saw that the seats had changed. I contacted support and they informed me that the tickets were final sale and that I should "use them", even after I said I'd already purchased two more from them at the same price, and "me and my partner are the only two people I know crazy enough to pay 4000 for this", and these tickets were ineligible for resale on the site.

They spoke in circles, and in one message, did confirm that "we told the others who had this issue the same thing", meaning they knew it was not an isolated incident.

They told me that SeatGeek offers this seat switching service, and they tell you they switch the seats. When I said their site malfunctioned because I didn't get the acknowledgement prompt they described, they would describe the functionality, and reiterate that they showed it to me. When I say "can you prove you showed it to me?" They would send me screenshots from someone else's sale as "proof". When I point that out, they say "you should use the seats." When I say I literally cannot do that-- "we showed you we switched the seats."

They kept trying to say they couldn't cancel the order and would change subjects if I said "fine, a refund then, for these tickets I didn't ask for." They would put the onus back on me "maybe the event will let you sell the tickets a few days before the concert. That happens sometimes..."

The runaround continued like this for a month. They wasted so much more money talking to me than just refunding. They never budged, and I ultimately only backed down because I filed a dispute with my credit card company to get my money back instead. 

Now, I still have the tickets, and I got a notification that the "terms and conditions for your event have changed". There's all these extras piled in with these purchases, and they send the codes for both purchases in one email. I'm terrified that they are going to ban me from this site or decide that actually they can cancel all of the tickets by trying to say I'm defrauding them or something. It's like they're trying to trick me into messing up. 

But at the end of the day, what I said is true. I have four tickets, all final sale, and only two butts with heads crazy enough to pay 1900 dollars to see The Weeknd.
