If ti is amazon that fulfill the order there is no way to know until the item is shipped
Luckily I am an Amazon Prime member and everything I ordered so far arrived the very next early morning, even if I order late evening early night
in my case they use a private same day / next day courrier, had no issues so far, I would for sure refuse ANYTHING from DHL even if they had it delivered the same day
There are horror stories with DHL and other fast courriers throwing packages, stealing, delivering to wrong addresses etc - I guess some areas seem more affected than others.
Try to contact AMAZON support and ask them if there are other alternatives for shipment in your area, usually when you ship you have a choice between speed of shipment, do you have this in your case ? If you can settle for longer shipping times, for sure they would not ship by DHL and might use regular postal service or some other carrier, or maybe not
I guess it would be best to ask, unfortunately, AMAZON's support is less than stellar which is shocking.
