Amazon - Package was not delivered and the Delivery boy was arrogant

We've ordered * Step Ladder through Amazon, and I think that Amazon has routed the delivery service to Delihvery.com. As per the schedule, they should deliver the product to my home on **-AUG-****. But, they were telling that they could not reach my home as road is dirty, and truck cannot go. But, in fact, the road is very clear in front of our street. We have one car, and one two-wheeler where we use everyday through that route.

When we call the delivery boy on +************, some other person is taking the control of that phone and he is scolding us using abusing words. I'm not sure whether he is in drunken mood. But, his terminology was so annoying where I cannot write here.

He was telling us to contact the customer care team if we really need the product. What do he mean by "if we really need the product?" Why do we order the product if we don't really need it? Who is he to shout on us? I want justice on this. I'm ready to go till anywhere to get this resolved. I think that Delhivery service management should give training to their employees and learn them on how to talk to customers.
