email receipts

Has anyone experienced NOT receiving a receipt from an apple store purchase? I spoke to the store and had them resend twice to a specific hotmail account...never came, not in junk. Then had them send to a different hotmail account...nothing. Then had them send to my iCloud email account and it showed up immediately. I have always had my receipts go to my default hotmail account. And now, it seems like I may not be receiving the receipts for my monthly iCloud storage. I usually receive the 20th of the month and as of 11/21, today, I have not received that particular receipt. I do not have any email rules set up and check my junk and deleted folders. Nothing.
