PayPal Buyer Protection
When you shop from sellers that accept PayPal, you may be eligible for a refund under the PayPal Buyer Protection Program. If applicable, through PayPal's Buyer Protection Program, you will be able to receive full reimbursement, including the purchase amount and original shipping costs, if any. PayPal will determine if your claim for compensation is eligible for the Buyer Protection Program. PayPal's original decision is final, but if you now have new or persuasive information that we did not have when we made the original decision, or if you believe the decision process went wrong, you can appeal the decision to PayPal.
Important: During the process of resolving a claim, you may need to return the item to the seller or another party designated by PayPal. The PayPal Buyer Protection Program cannot reimburse possible return shipping costs.
The PayPal Buyer Protection Program may apply to the following specific transaction issues:
You have not received the item from the seller (called a "Item Not Received" claim), or
The item you received was not what you ordered (called a "significantly different from description" claim for compensation).
If you believe that a transaction made through your PayPal account was not authorized by you, this type of compensation claim is different from the Buyer Protection Program.
So we have no direct relationship with your funds, all funds are guaranteed by third-party platforms, so there is no insecurity,
