Coin Packages- Jackpot Party Casino

I have been buying coin packages for about 4 Months. In reviewing my credit card, I've noticed sadly that I am being charged multiple times for maybe some buys and also being charges for buys that I did not make!!!

There was a charge on my credit card for TODAY 3/26/23 AND I KNOW THAT I DIDNOT MAKE A PURCHASE!

How do I start and who do I contact for this problem? The Apple.com website is for maybe a few payments problems.
