Bad delivery service

I have never experienced such a bad service ever, more especially from a big international logistic company like FedEx... I was called Sunday by their consultant confirming my details since my productwas going to be delivered on Monday and I gave all my necessary details. The following day my goods were never delivered, I called the person who promised the delivery, no one is answering. I have been calling since yesterday... I also don't go through even to in their customer service number that is found onlin:***... I have never ever experienced such unprofessional and bad service in my life. My business is on hold
