Hello, this message is for Marisol Vega. It's Trevor Nakamura calling from Delgado Office Interiors about your order of twelve ergonomic desk chairs. Unfortunately, the gray fabric model you selected is on back order, and our supplier can't ship it for another six weeks. However, we do have the identical chair in dark blue in stock, and we could deliver those as early as Monday. There'd be no change in price. Could you call me back before five o'clock on Thursday to let me know which option you prefer? Otherwise, I'll have to move your order to the end of the delivery schedule. Thanks so much.
