Same thing continued again i received a message on 31st that its delayed by 3 days and it will reach to you by 2nd november. And again its delayed
I talked to customer care executives they are unable to do anything and just giving fake promises. After calling to customer care to find solution from higher authorities they told me "higher customer care authorities are busy in sells so not able to attend customer calls" even after waiting for more than 30 minutes for their response.
Will u please return my money and cancel my order if you are unable to deliver it.
The shipment gets misrouted twice after coming in my area perimeter (5-8 km away).
No responses from customer care just fooling the buyer.
