A really bad experience and I'm wondering if I will get my package

A very terrible experience I've ever received with a courier company. Ive never experienced such a distress with a courier company, this is my 1st time working with them and it is such a terrible experience.

My package was suppose to be delivered yesterday then someone from the FedEx drivers decided to update an incorrect information that I was not at home and I was unreachable. I was home the whole day yesterday and today even, but I haven't received my package. I phoned the company more than 5 times and I'm getting different responses, the last call they told me it is with a third party company and they will deliver at 5pm it after 5 now and I haven't received any call, I am losing my mind because I urgently need the package when my phone is ringing i jump to pick it up because I'm hoping it them, when I hear a sound of a car near my house I go out because I'm thinking it my delivery. The watsapp chat bot is not helping at all, this company needs some serious intervention with the level of service they provide.
