Chances are, you weren't overcharged at all! Sometimes when our system submits a charge your card issuer will place a temporary hold, which can appear for a different amount from your order. We have no control over whether this will happen or how much your bank might hold. Rest assured that when your bank clears the transaction, the pending amount will fall off and the amount paid to oVertone will match your order confirmation. We recommend contacting your bank if you need more info!
