Poor Service. Poor communication. Poor logistics company.

Poor service. They sent me an email and SMS saying delivery will take place yesterday at 08:00 in the morning and then nobody came to deliver. the online tracker is showing the same information as it did yesterday so I have no idea what is happening. Tired calling them and get an automated service which transfers you but then someone just reject the call. Tried their online chat but nobody responds. I personally have to be here to sign for my package so I have now had to reschedule meetings but have no idea when they might come. If you are not able to deliver on a specific day then don't tell the client the parcel will be delivered, rather say it going to be another 2 days so people don't waste their time waiting for you and then getting annoyed when you don't deliver.
