I'd say a lot of delivery companies are going this way...seems like it really spread during the pandemic. For example, Hermes is uncontactable despite appearing to offer multiple ways to contact customer services. When you try any of them, you just get an automated system (either a telephone menu system and pre-recorded messages or a webchat bot) and there is no actual way to get to speak to a human. Fine if everything is going well and you just need a status update but you are screwed if there any problems.
I had an issue with a delivery that went missing by Hermes about two months ago. Said it was out for delivery, never arrived, then the status said it was back at my local depot. It never arrived and there is no way to get into contact with Hermes to sort it out.
