We hired a vendor to build wine lockers for our new restaurant. After months of delays from the vendor and them no longer responding to us we realized they went out of business after 38 years. This vendor did not notify us at all and we had already paid them a large some amount of money. We called American Express to see if there is anything we could do and they immediately agreed to dispute this and reimbursed all our money that we paid the vendor. We are very grateful and do not feel any other credit card company would have stepped up they way they did for us. Thank you kindly!
