Beyond horrific customer experience

I placed an order on 17 October and delivery was confirmed for 18 October. On said delivery day, I was not at the delivery address and received missed calls from a landline no. which few minutes later, I found out was from NetFlorist. I called the no. back several times but it did not go through. Alas, my order was not delivered because the driver "couldn't find my location". I've used NetFlorist before and the driver found my location without issues previously. Secondly, why was I not notified via WhatsApp as they had been doing all along instead of using a no. that doesn't accept incoming calls? I rescheduled the delivery for the following day to my work address. There was no communication whatsoever from them until I made follow-ups. I was given excuses about the driver's whereabouts when I wanted to track my parcel. The driver eventually arrived (after 5PM), my parcel was given to a colleague - no call, nothing to say he was there. I will NEVER put myself through such a horrific customer experience when there are other options available.
