No accountability for merchandise not being delivered

I placed an order on Amazon on the 19 of July 2017 and the estimated delivery date was 24 August 2017. I sent them a mail at that time to request where my order was and was referred to the supplier who was no help either. I recently sent another mail to the supplier as I have not received my package yet and they responded by sending me the tracking number. I have already checked with the Post Office and no-one knows where my package is. So now neither Amazon nor their supplier will do anything to assist me with getting this package. They have no problem taking your money and once they have it, its not their problem anymore. It was the 1st and last time that I will ever buy anything from Amazon ever again and will make a point of making everyone aware of how they conduct their business.
