Why was I charged twice/ over-charged?

1. If you are being charged a second time:

• If you pay through Paypal, the second amount might be a pre-authorized charge from PayPal and it will eventually fall off your account. We highly suggest contacting PayPal to turn off or remove the pre-authorized setting in your account. 
• It may also be a pending transaction when paying by credit card, so please kindly check its status. It appears on your bank statement along with the real payment and will disappear within a few business days.
  
• You may have used installment payment, please check your payment settings
  

Please reach out to us if you do not see any changes on your account within 5 - 7 business days and we will help to check it out.

2. Over-charged: There is only one transaction, but your side shows that the amount deducted from the account is greater than the original price displayed in the order confirmation email.
