Review Horrendous delivery service

Courts mammouth delivered several items for me...they never called in advance to let me know the day or a few days before...they call when they are in the area...they called saturday 18th of september at 12:02 trying to deliver a Bosch Cooker Hood...since they had not called me before I was in Port Louis...on Tuesday 21 of September they called again but this time they had shipped it to Bel Air instead of Grand Gaube...when I called to speak to a supervisor they asked that I left a phone number for one to call...it has been over an hour and no one has called...looking at their terrible rating here I doubt anyone cares over there and I don't think a supervisor will call...
