Never Recieved Email Confirmation or Order Number

this is my last resort

i ordered a pair of Ray Ban Meta Glasses thru the Meta website 
when i checked out, i checked out not making a login to Meta account nor my facebook account 

after check out, i recieved a notification that an email confirmation will be sent to my email 

i was charged on my credit card immediately and its been 2 days since the charge

i cannot get into contact with anyone at Meta about my order number or email confirmation 

last thing i saw was ETA of the delivery was shown to be 08/21 before check out 

how do i find my email confirmation/order number if when i checked out 

i never logged in 

has this happened to anyone? 

this is very frustrating cause i might have to dispute the charge on my CC cause of no verification of my order
