Subject: Price discrepancy
I am writing in relation to the invoice we received from you yesterday.
The invoice stated that we ordered 1000 units of part XYZ at \2340 each. Is that price correct? After our phone conversation earlier in the week, I thought it had been decided that we would only be charged \2200 each, because of the numerous delays we experienced with our order.
I would appreciate it if you could confirm the price and issue us with a new invoice as soon as possible.
Thank you in advance for your assistance in this matter.
