We have been expeting our package with tracking # EJ240295635US, it is priority mail and should have delivered at 12Noon. It is 3:45PM have not received package. They should at least call, what's the point of adding that information if they don't call, they are lazy. This is not the first time and has been happening every so often. This is payroll and time is of the essence. Please call me Wilma Del Rosario at (562)739-0637 Thanks, Tracking number EJ240295635US Tracking number created Package received by USPS In transit November 10, 10:37AM Los Angeles, CA Out for delivery November 10, 10:48AM West Hollywood, CA Delivery failed November 10, 11:52AM West Hollywood, CA
