A former Walmart employee filed a lawsuit Friday against the company regarding records they claim to be false.

The lawsuit claims Walmart filed misleading e-commerce reports as it competes with Amazon for more business.

The plaintiff also claims he was wrongfully fired for issuing a complaint about the reports.

Walmart released a response to the lawsuit, saying in part, “We take allegations like this seriously and looked into them when they were brought to our attention. The investigation found nothing to suggest that the company acted improperly. We intend to vigorously defend the company against these claims.”
