Receipt

I need to get a copy of my receipt purchased my iPhone 12. And I purchased it online and I believe it was January or February 2022. I don’t have the card that I originally use, but I do have the IMEI number if that would help. I’m having problems with the phone And I need to have Apple fix it but they need a proof that I bought the phone. So if you need the IMEI number just respond to this and I will get you that number.
