Ticketmaster complaint: Ticket Refund due to changed date / venue

I had a ticket for Limp Bizkit on 16th April 2023. The event was due to take place at Brixton Academy, the venue was then changed to 16th 17th at Wembley Arena. Then these dates were changed again to the 17th and a majority of people who had standing tickets were given seated tickets due to lack standing room.

Because of these we were given the option of a refund, I asked for a refund before the shows date, was told someone would get back to me. I heard nothing but a few days later tickets master responded in their chat ing that I wanted a refund, i was given no indication or email that ticketmaster had responded. When I did log back in and saw this i responded but again was met with ticketmsautomated response of we are awfully busy someone would get back to me. Days later when someone did get back to me they said they can no longer refund me due the the date of the concert had passed.

This is not acceptable, i have been patient, waited for someone to get back to me, but because it appaears they dont have n staff I am being screwed over.
