Ridiculous Customer Service from Zando

What is going on with Zando's customer care division. I ordered items on the 8th of May, and was informed that delivery would be done between the 15th and 19th of May. I have been following up with them on email and on Twitter for 2 weeks now, and they confirmed on the 1st of June that there was an issue with Dawn Wing and their system, and my order would be delivered in that week. Surprise, surprise, upon me following up for the umpteenth time today, I was told that the delivery truck was hijacked. If that is really the case, could they not contact me to inform me, instead of me having to following up with them for weeks on end. Why would I also now receive an sms informing me that my order is "delayed" due to the pandemic. This is such ridiculous service from Zando.
