Dear Richard Anderson,
I was surprised to receive an incorrect statement of account from you yesterday. You might have forgotten that our agreed price for the painting is $600 and not $750. I am hoping that we can solve this matter as soon as possible. Our good business relationship is important for me and I would be glad to refer you to some of my friends and family who might be needing your services. Kindly send me the correct statement of account. Thanks.
Sincerely,
Vaishali
