Ticketmaster complaint: No Refund on Ticketmaster Technical issues

I bought 4 tickets for a boxing event for the sole purpose of the Main Event title fight. That main title fight was cancelled, I asked for a refund through the website prior to the event, Ticketmaster sent an email stating that the event was rescheduled, the event was NOT rescheduled and went on without that title fight. I have been going back and forth with them through email too many times. No one is looking into the details nor getting any facts straight. See email trail below;
The Main event was cancelled that day of the event. Through Ticketmaster’s difficult website I notified them of my request for a refund. I received an email back that the event was rescheduled when it really was not. That might have been a Ticketmaster technical issue. Regardless this whole event, Ticketmaster, and this promoter are frauds. I will not stop until every website knows how slimy Ticketmaster is. Link attached below.

Thank you for reaching out. The event you are inquiring about has been rescheduled.
We have worked with the event organizer to reschedule your event and make sure you still have the chance to attend. Your tickets are still valid for the new date. Please note that your event organizer is not allowing refunds at this time.
You can always check your Ticketmaster account as any changes to the event or your order status will be posted in your Event Details. If a refund button appears, this would indicate that the event organizer has made your order eligible for a refund. If the status of your event changes, we will be sure to email you with the new information, as well as options made available, at that time. Please be aware that, at this time, we do not have any further information regarding your event.
