(Reuters) -The department store chain Dillard's sued Wells Fargo ( WFC ) on Thursday, saying the bank repeatedly breached a since-abandoned co-branded credit card relationship, causing the department store chain tens of millions of dollars in losses.

Dillard's filed its lawsuit in Manhattan federal court, less than a year after being "shocked" to learn that the fourth-largest U.S. bank had decided to abandon the co-branded card market.
