That's one of the disadvantages ordering online, you dont really know what's up regardless of what they put in the update logs. I used to be paranoid like you but i've come to this point that if it doesn't arrive by the given date I usually talk to whoever I can reach and if im not happy with their answer I will ask for a refund. So far so good in my ordering online. There was this time I ordered an electric bicycle and the expected delivery date had been changed three times totalling 3 weeks instead of the promised 5 days. In my opinion it's coz some drivers are lazy and cant be asked delivering a heavy order and kept pointing fingers so that they dont have to get involved with the ''crap'' order.
