Amazon India — cheating delivery dates

They show some dates during the time of order, after that they some message of some other dates of expected delivery, and further more they are delivering it some dates later.
Customer care service is worst, all they can say all the time is "we will take a request" repeatedly every time we call.
People who are working in hubs and delivery persons are worst in the world,,,,, they would simply skip the delivery... Depending upon their convenience. They dont call you, but you'll keep receiving message 'we tried to contact you but cant reach you, so it will be delivered tomorrow'... And simply keep on postponing dates...
They try to push customers to buy amazon prime for promised delivery dates
