Amazon has always been good at providing facility like customer service , refund and return facility.
I hv bought many things from amazon and always they have delivered on time. Delivery time taken by amazon is the least as comparrd to its competitors.
The product quality of each and every product that I hv purchased is the same as shown on the website or app. You can trust on amazon blindly.
Also the return facility of amazon is very good. Whenever u will ask for a return and refund. The same will be done on time.
You could say these guys are really punctual and that is the best part of it.
