Zero Customer Service Experience

The 1 rating is even a lot, I placed an order online on the 25th of April 2025. The order was supposed to be delivered on the 5th of May 2025, I received an sms in the morning as well as in the afternoon to say the driver is on the way to deliver my parcel. The driver did not arrive and I wasn’t even notified that the order is delayed or whatever, only for me to be called today the 6th of May 2025 to be told that some of the items I ordered are out of stock. On the time where I am expecting to receive my order, what do you call that?
