UPS review: Guaranteed delivery

I ordered a car part from Amazon on 2/18/20 and was guaranteed delivery by Friday 2/21/20. When it did not arrive I called the CS number on Saturday and they said the UPS office was closed for the weekend and that they would submit a DC/concern and someone would call Monday morning. No one called so I called CS again. They had no record of a concern or anything. The web site said the package was in Odessa, TX. I called the warehhouse there. The package was indeed there but they needed an address update because their driver couldn't find the address. That is ridiculous since it is a 911 address and you can Google it and get detailed drive instructions. I supplied my phone number and detailed instructions on how to find the address. They said it would be delivered today. It was not delivered so around 5 o'clock or so I called CS yet again. And again, I gave detailed information about the delivery address. I spoke to the 2nd tier supervisor who could not resolve the issue and then spoke with the 3rd tier supervisor who assured me it would be delivered that very evening. By 9 pm nothing had arrived. I called CS yet again. Now they said it had been put on the wrong truck and would be delivered Wednesday which is over a full week since I ordered and four days past the guarantee date. The supervisor after nearly 30 more minutes on the phone offered a 40% discount on the next order. I asked them why I would ever want to use the service again after this fiasco. I don't want anything but the package I ordered and compensation for the guarantee date. The package was a part to fix my husband's truck so he could go to work.He has had to borrow a car from a friend just to get to work. And he is working 360 miles away from home so he needs his truck to come home on his days off. In conclusion, this has been the worst delivery experience ever and from now on I will deal with another carrier. Such unprofessionalism in a business is disappointing to say the very least. I am furious at the runaround I received from the employees. They kept promising delivery and all they succeeded in doing is wasting my time. The website gave no updated information after 4:08 this afternoon. The automated phone response said it had no information and that maybe a ticket hadn't been made out for it yet. I plan to advise Amazon about this as well as put a complaint on every review I can find. No excuses for shoddy business practices. #1Z81WV500301417586 Reference
