All shipments are scanned whilst moving through the automated section of the network. In the event your item is scanned and recorded as being larger or heavier than the allowance that was purchased on your order, our system will automatically send a notification requesting the fee for the additional size or weight that was sent. Any additional weight or size used will never cost more than it would have cost at the time of booking. You can pay this charge by logging onto your Send My Bag account here or by calling the Send My Bag team.
Should you feel that the charge has been applied in error, and that the weight or dimensions used during booking are correct, you can respond to the over allowance email you received and a member of the relevant team will get back to you explaining how you can dispute the charge.
