Dear [Title] LAST,

We have ordered [quantity] [products] on [date] (invoice no: [number]). 

The price of [product] quoted to us was [price] [with a discount of [%]%]. However, the invoice sent to us has included very high [freight and handling] / [other charges] which was not in the original quotation. Could you please explain these charges?

As we have not been [expecting / budgeting] these charges, it would be greatly appreciated if you could [waive / give us a discount] on these charges [or we shall seek a full refund on the products].

Your assistance is very much appreciated.
