作文：由于发票错误抱怨(For Errors in an Invoice)

dear sirs,

when your sales representative,helen xu,called on me in late december,she told me that you were offering a special price of $ 147 on the,wizard icemaker during the month of january.i ordered six on january 17,figuring the total amount of the order at $882.however,the invoice that accompanied the shipment showed the amount due as $ 1098.it is apparent that i was charged the regular price of $ 183 instead of the lower price i was promised.

im enclosing a check for $ 882 in payment of the order.unless i hear from, you to the contrary,i will assume that this is the correct amount and that my account is clear.if this is not the case,i would like your permission to return the six wizard icemakers to you at your expense.

sincerely yours,
