Name linked to icloud email address spelled wrong, and cannot change

I obviously set it up with a typo in it the first time but I’ve now been through My Card settings, iCloud settings and Apple ID settings… all have the correct name… Finally found the typo under email aliases (this has been an absolute nightmare to get to this point btw… obviously my fat thumbs failed me setting it up in the first place but seriously what a confusing jumbled mess of name and ID settings… anyway, found it, changed it…. Confirmed that I changed it……. ITS STILL SENDING WITH THE WRONG NAME!!! Can someone please help??!
