BANGOR, Maine (AP) _ A Maine wreath maker has sued FedEx for allegedly overbilling it by more than $350,000.

The Bangor Daily News reports that the parent company of Worcester Wreath Co. filed the suit in federal court last month.

The suit alleges FedEx was supposed to bill Amazon for the shipping of wreaths sold through the online retailer last holiday season, but instead charged the wreath company.

The suit says the company continued to be billed after notifying FedEx, and some payments were drafted directly from the company’s bank account. The wreath company said FedEx threatened to stop shipping their products when payments were withheld.

A FedEx spokesman said the company is reviewing the complaint and takes the matter seriously. He said the company wants to have a “thorough understanding of what happened.”
