Warehouse out of stock

I visited 4 branches this weekend, hoping to find 1 branch that have stock of the LG G4. NOT ONE. The only reply is - the warehouse is out of stock and the branches have no idea when they will receive stock. One of the branches told me that they ordered the LG G4 for other customers a month ago and still not received stock.<br> <br> Now explain to me how do you advertise products, you don't have stock of?<br> <br> Employees at branches simply pull up their shoulders on losing customers which I understand - after a month of receiving no stock I would also have no idea how to explain anything.<br> <br> This is a management problem!
