On 9 September 2016 we placed an order with your firm for 12,000 ultra super long-life batteries. The consignment arrived yesterday but contained only 1,200 batteries.
Firstly, I had difficulty in registering to attend the event. You set up an on-line registration facility, but I found the facility totally unworkable.
You sent us an invoice for $10,532, but did not deduct our usual 10% discount.
We have found 16 spelling errors and 2 mis-labelled diagrams in the sample book.
Effect:
This error put our firm in a difficult position, as we had to make some emergency purchases to fulfil our commitments to all our customers. This caused us considerable inconvenience.
Even after spending several wasted hours trying to register in this way, the computer would not accept my application.
I am therefore returning the invoice to you for correction.
