Delayed delivery with no communication

I placed an order on Zando a week ago and 2 days after placing the order it was shipped. Since then the status has not changed and when I contacted the support team, I was told that the order was out on delivery 18th Sept. I followed up on 19th September, and I was informed that the new courier company DPD Laser is not allowed to contact customers for delivery. It's been 3 days and I have not received my order. Why the heck did Zando contract a third party courier company that is not allowed to make direct contact with customers and how are we suppose to guess when the driver is at the gate or reception of big organizations?? The former drivers were quick and very efficient. I've been using Zando since 2017 and this is by far the worst experience 🙃 😔. Please change the courier company!!! I need my order delivered ASAP!
