Event tickets center Overcharged me for tickets by 267%

I paid $294 for two tickets plus a service fee of $97.02 plus a delivery fee of $7.95

Tickets 2x $147           $294

Service Fee 2 x $48.51  $97.02

Delivery                        $7.95

Order total                  $398.97

When the tickets arrived they were $55 tickets

I called them as soon as I received the tickets within 24 hours asking them to refund my money as I felt ripped off.

I spoke with a gentleman called Greg (he wouldnt give me his second name)

He refused to refund my money and told me it says on their website all ticket sales are final and that that will hold up in court. 

When I mentioned that there should be a class action lawsuit, he said "Do it, Do it" and told me they can charge whatever price they like for the $55 tickets.

Its a total ripoff and they absolutely refuse to refund my money.
