Universal trade
12 October 2014  

 Dear Sirs,
Invoice # 357890

I regret to inform you that the above invoice contains a mistake. It is almost certainly the case that the figure in the invoice for the total has been multiplied by a hundred. In view of our longstanding dealings with your company, I’m convinced that you do not expect me to pay 98000 dollars for the last delivery of switches and electrical components.
I would very much appreciate receiving a more reasonable invoice.    

Yours faithfully,
Jim Brown,
Chief of purchasing dept.
