If you've made a purchase on FunPay, you shouldn't expect that the website will automatically give it to you. The seller executes the order manually. For example, if you bought an account, the seller will give you the account data via the website chat.
Therefore, please contact the seller before making a payment (to discuss order terms).
For in-game delivery (for example, when you buy in-game currency or items), we recommend you to stick to the delivery method the seller proposed, since they are usually more experienced in these matters.
