MTCGame Charged My Card $55 Without Authorization

On May 29, while attempting to purchase a Museum Card through the MTCGame website I was directed to, I entered the verification code sent to my phone and then discovered that $55 had been charged to my card without my knowledge or authorization. The card belongs entirely to me, and I had no intention of purchasing any game or digital product through MTCGame, yet this transaction was still completed.

Because it was a public holiday, I was unable to contact my bank or MTCGame at the time. However, the $55 charge is clearly visible in my card transaction history. I absolutely did not authorize this transaction and had only used the page I was directed to for the purpose of purchasing a Museum Card.

I request the immediate refund of the unauthorized $55 charge and a thorough security review to ensure that my card information is not used without my permission.
