No delivery and terrible customer service.

Unfortunately, they were unable to deliver because the office premises were closed on Saturday, I am using my work address. When I called the call center on Monday morning after receiving a notification that the package will be delivered, I was not helped, therefore it was a waste of my airtime. Why can't the call center get in touch with the driver and find out what's going on? As a customer, I can't get in touch with the driver; I can only get in touch with the call center. Now, picture calling the call center to ask for help, and they are unable to help either because they don't know where the driver is or can't call the driver as no one can help and they don't keep the driver's numbers. The driver returned my package to the warehouse later that evening while I was monitoring the status of my delivery. The notes stated that I wanted to postpone the delivery, which is a lie. How did I do that when the driver never got in touch with me and the call center was unable to assist me? Nobody is available to help, and no apology has been sent for the unsuccessful delivery. There is no purpose in using chat services because that too is just for show, you literally chat by yourself. Whatsap service does not work. I am beyond disappointed in their service.
