资料题：How much should be subtracted from Ms. Hoffman’s bill?

Please make all checks payable to The Glass House.To report any problem, contact the sales representative who took your order by e-mail or by calling 555- 9773.Thank you for your business!   Dear Mr. Smith,l would like to report an error in my latest glassware order with the reference number 200-367777. I specifically requested three cases of Rosetta champagne glasses in the previous e-mail l sent you. However, when my delivery arrived at the restaurant yesterday, there were four cases in the package, which is also specified on the invoice that came with the delivery. In other words, l was charged for a case that l did not order. In addition, when I opened the other boxes, l found two sherry glasses with broken stems.I will be returning the extra case, along with Ihe broken sherry glasses, and assume that you will cover the cost of shipping. In addition，l ask that you replace the damaged items as soon as possible. My assistant manager, Catherine Simmons, will be calling you this afternoon to work out the details.I have attached a copy of my last e-mail for your reference. 1 hope you will address my concerns immediately and take measures to prevent this from happening again.Sincerely,Abigail HoffmanProprietor, Studio Bar and Restaurant
