Dear John harrison,
It was with a great deal of surprise that I received an invoice yesterday for $2,000. The agreement made between us clearly confirmed that I would only pay $1,600 for the kitchen units. As we have always had a good working relationship I would hope that a correct invoice can be quickly sent out, so that I am once again able to provide excellent references for your business. Many thanks.
Sincerely,
Lisa parker
