It's difficult to answer with no information. What is the shipping rate problem? Was the buyer charged less than what the label is costing you? It's the seller's responsibility to have the correct information on the listing so if you charged too little, you can't bill the buyer for more now. You'll have to pay for the extra shipping.
If the problem was something else, please give us more info.

Looks like they sold a hoverboard and entered 1st class USPS as the shipping method at $5.25.
