The Professional Couriers — The package was not delivered but on website updated as delivered

This is really so unprofessional of a courier service whose name is Professional Couriers...
I was expecting an important package since morning of 24.11.2021. When I called the branch they assured that it will reach by 4:30. Tracking ID is CCU20821288
Then I checked the website to track the shipment again and it said the package has been delivered around 12 pm and has been acknowledged and signed. This is so ridiculous tat I have been waiting for the shipment and did not receive it till evening and it said it has been delivered.
when i tried contacting the courier branches they kept on transferring my call without understanding the importance. Then one of the branch responded very causally that this is a mistake that the parcel has been wrongly delivered to someone else.
this is Highly disgusting and regretful to see that you people are so negligent about customers packages and you hire unprofessional courier people who cant probably read the address.
I would highly NOT RECOMMEND your courier company to anyone. I have faced a lot of harassment and would never rely on such a courier service provider.
