Online boutique Chick Downtown has defaulted on a $950,000 line of credit from Enterprise Bank, according to a lawsuit brought earlier this month by the lender. The suit, filed Dec. 15 in the Court of Common Pleas of Allegheny County, Pa., seeks $972,830.46 from the Pittsburgh-based e-commerce operator for the remainder of its principal and interest and attorneys’ fees. The bank’s complaint is the latest in a string of recent lawsuits filed against the online merchant. Several creditors, including Mint Collection Inc. and Molli Enterprise, have filed lawsuits accusing the company of failing to pay debts. A number listed for the company was disconnected when reached Tuesday. The retailer closed its brick-and-mortar location in Pittsburgh earlier this year.
