ORDER #[protected]
Ordered product : Redmi note 3
This order was placed on 16-march 2016. I was out for some work and handed money to neighbour to recieve the product. At 6:10pm 20 march 2016 I got a message saying your order was rejected by you. Immediately I called the customer care with the issue but they said they cant do anything and said some other person will help me with this.Then someone called and asked to wait 24hrs. Again I called after 24hrs again they said to wait another 24 hrs.This time I asked them to contact higher authority So they handed the call to Mr. Shahnawaz (Pune). He made a new story that delivery boy has a software in which REJECT button is activated only after talking to customer for 1min 30 sec to 2 min and said Delivery boy talked to me and I asked him to reject it.
How is that even possible, I can verify with help of Airtel that no one called me and I didnt talked to them .
When I asked him for Delivery boy number so that i can crosscheck, he refused saying confidential.
I asked them to add to cart in next sale, they refused for that also
