I'd recommend writing to email@example.com. Because they will not share your personal account details via this community page.
Also, make sure the about the network fees;
Ethereum network charges a high transaction fee.
Debit card or Credit card purchases incur a transaction fee.
Paypal transactions incur a high transaction fee.
It depends on the network.
