Failure to deliver

I have been waiting on a package to be delivered since the 4th when it was originally out for delivery, its now the 6th and I have yet to receive my package. I have made multiple attempts to correct your issues. I have called the call center multiple times only once been helped after waiting 20-30minutes everytime, I was told a note would be made that the driver contact me. I have seen the notification 3 days in a row that its out for delivery not a single time have i been contacted for an actual delivery. Everytime i check the tacking it just says unsuccesfull delivery -home - contact unavailable. Which is completely untrue because ive been home all day all 3 days and my phone on infact like stated earlier ive been on the phone with the help line so clearly it works.
