I found a services that will unlock my phone, that is blocked în a certain network at this moment. The seller tel me to send the money to a email linked to his PayPal account. If I do that, and I will not receive the unlock code promise, is there a way to be refunded by PayPal?? My tranzaction is covered by PayPal policy? I ask the seller to create an invoice for this unlock proces, and he answer that," paypal invoice creation process is not working properly in my account: Pay to the email provided" Is a scam or not ???
