order never went through but they still charged my card!

So I went online on cricket to switch over to them and get the free iPhone se if I switch over my phone number deal and when i got all the way to the end of checkout they said they couldn’t process my order and to try again later but they still charged my card $180!! I never got an confirmation email for the order nothing but I’m sitting here at 11:44 pm and my bank just gave me a notification that the charge from 180 from cricket has gone from pending to completed! I’m freaking out cuz my current iPhone SE is broken asf cracked screen and I need a new phone before me and my husband move back home in match , I tried to do the order again and it told me they’re already trying to switch my number over to cricket so I’m so confused where is my confirmation email?!
