Ecom express was the courier company, they gave estimate delivery date as 10 days.
On 5th day it reached my nearest location I asked customer care it is now near my hub and status shows arrived at wrong address, he told I will send a mail, again after 3 days I called they told it will be delivered I am sending them mail, again today I called they says sir ecom express will have to deliver, we are really sorry but you have to wait.
No ordering paying money upfront and 30 min of customer care call, after this nothing I have, there services are going like Snapdeal, Flipkart is best, please avoid Amazon for any area other than capital cities, there should be a policy where they will have to give fine for this
