First, head over to PayPal or whichever banking website, make sure that a charge was depleted from your account. If not, the transaction never went through. Either you accidentally didn't press the "Confirm Purchase" or your card might of be declined by your bank or card itself. If it seems like a payment has gone through, make sure to sign in to the correct discord account that you used to purchase the model when you purchased it. If none of these options worked or you're unsure about the method, you're more than welcome to open a support ticket in this discord.
