Vivid Seats review: Unauthorized charge

On September 1, 2025, I was charged on 2 different credit cards for very large sums of money for 4 tickets to the Buffalo Bills Game at the Bank of America Panthers Stadium. I did not order them. The 2 sums are from US Bank Credit Card $1936.57 and from Wescom Credit Union Knotts Berry Farm Credit Card $3832.61. Total loss is $5768.61.
First discovery was September 2, 2025, and I called the number to cancel the charge which I stated was fraud, the amount of $3832.61. The other I noticed was on September 5, 2025, when checking my bank statements. That amount is $1936.57.
The fraudster used my PayPal account to gain access which I rarely used and even added another card in my name which I had used to buy things online. The method of access was a very large security flaw in Microsoft Edge browser. Instead of expiring tokens when tabs went to sleep, the tokens remained live so anyone with access to my browser can use. The passwords were still protected by pin but since the tokens did not expire, there was no request to enter a pin code. This is an error on Microsoft.

The tickets were distributed and sold by Vividseats LLC in Chicago and processed by PayPal in San Jose. I live in California and will be taking this case to other agencies. At least 3 more. I want the matter resolved quickly and I don't want to hear I am going to have to pay the $5768.61 which represents at least 2 months of my income. I am 62. So, this is also elder abuse financial exploitation.

As of today, both charges appear on my credit card statement, and I am liable to pay. I don't want to pay for something Idid not order especially when the cost is so high. 4 tickets to a game you could probably see on TV for $5768.61?

I am not a sports fan. I did not make these 2 purchases. I need help in getting the money back. So far, all attempts to get the money has failed and I remain hopeless worrying how am I going to pay these 2 big bills.
