Q: Apple I.D. account hack

My apple I.D. account was hacked last night, and I knew because I had received emails 1) requesting to reset my password, and 2) stating my password was changed. unfortunately, they reset my password through my email. I am wondering who do I report to this? An apple email by chance. I also know who changed my password and the device.

I did take precaution and changed all passwords and unlinked all old devices. Also couldn't find the right community for this.
