Customers of Amazon.com filed a lawsuit against the online retailer in a Seattle, Washington, U.S. court, claiming they were charged for items they had promptly returned.

In the proposed class action complaint filed on Tuesday, four residents of Illinois, Minnesota, and Missouri claimed that Amazon “wrongfully re-charged the purchase price and applicable taxes” for their returns.

They claimed that Amazon knew about its “systemic failure to deliver on its promise of refunds for promptly returned items.”

There were no comments on the issue available from Amazon.

The new lawsuit was filed concurrently with reports that the US Federal Trade Commission was prepared to submit a complaint alleging anticompetitive business practises by Amazon.

Separate consumer antitrust actions against Amazon regarding its pricing practises are now proceeding in Seattle. Additionally, Amazon is being sued by California in state court for its corporate practises. In the cases, Amazon has refuted any misconduct.

According to Tuesday’s complaint, Amazon’s customer return policies have caused “substantial unjustified monetary losses by those who either do not notice” they have been charged or were “deterred by the inconvenience of having to figure out what happened and how to fix it,” the lawsuit claimed.

According to the plaintiffs, who are being represented by the law firm Quinn Emanuel Urquhart & Sullivan, millions of Americans over the past six years have reportedly been charged by Amazon after returning products on time and in their original condition.

Under the consumer protection legislation of Washington state, the plaintiffs are requesting triple damages in addition to additional remedy. When contacted for comment on Wednesday, their solicitors did not react right away.

Amazon has already been sued by Quinn Emanuel. The huge, nationwide firm is one of several law firms defending clients who claim that Amazon artificially inflated the costs of products listed on the company’s website. Amazon has denied any responsibility in the ongoing legal dispute.
