Ticketmaster complaint: Scamming people

I purchased 3 tickets from tickets master! We were to see Tim McGraw at the rodeo in San Antonio Tx. We got there about 1230 only to sit in traffic until about 330 which meant we were never able to get into the concert at all. I not only called and emailed so many times to ticket master for someone to help me either switch my time to the later concert or just credit my account. I was able to get ahold of one person on that following Monday which said wow I didn’t think it would be that packed I said yes it was bad! I took pictures of us in traffic so I would have proof us not being able to get in. The tickets were a total of 360.00 dollars which was my mothers birthday gift! The woman state she would put my claim in for me to get a refund! I waited about a week to only be told my tickets has showed scanned! I would love to know how that is possible when I am the only one who has the tickets on my phone also when I have proof we never went in! I want a full refund this is unfair and ticket master apparently is scamming people!
