Ecom Express — Misbehaviour of courier boy

Address:

#33,Krishna Nagar, Home

I recently placed an order from forever21 it was to be delivered to me by Ecom Express. Suddenly day before the courier was to be delivered the price of the product that I placed an order from forever21 reduced.So, I just thought of placing an another order of the same product from forever21 at lesser and thought refusing the order (that I placed with higher price)at the time of delivery.When I refuse to take the order the courier boy misbehave like anything you can't cancel the order my petrol is wasted this and that and even gives me threat that he will not deliver my prepaid orders in future. This is not the behaviour a courier boy should carry with him .Ecom please take legal action against him as soon as possible
