Dear Felix
I’m afraid there has been an error.
This is the [ORDINAL, ex. third] time your firm has attempted to ship [PRODUCT (S), ex. 50 toner cartridges] to our office on [DATE, ex. June 9, 1998]. We would like you to know that no such order for [PRODUCT (S), ex. 50 toner cartridges] had been made. We absolutely reject the shipment. Please arrange to pick up your product {s} as we are not willing to incur any expenses to return them. Furthermore, your invoice (#[INVOICE NUMBER]) and this letter has been forwarded to the Attorney General of [STATE/PROVINCE, ex. Ontario] for possible fraud prosecution.
Regards
Lydia
