I placed an order for water storage heater vide I'd no[protected]. The item was despatched on 12 th nov 2016 and intimated date of delivery at Bhubaneswar at my residence was 24th nov. I made the payment in full. On 24 th I received a message from the courier Gati that the item was out for delivery and cell no and name of delivery boy was also given. When nobody turned up till evening I rang up the fellow. He said the vehicle broke down and the delivery will be done next day. But immediately after that a message came that attempted delivery by the courier had failed as I requested for postponement. I immediately wrote to Amazon through facebook that this was false. They said they will check up. Next day I complained to Amazon through their chat option that the delivery boys are reluctant to make such deliveries due to the size of package. They again assured that delivery will be done in 24 hrs. Delivery did not happen on 26th. So again through chat option I informed Amazon. Again assurance that delivery will be done within 24 to 48 hrs. On 28th I get a message that delivery is returned due to one of several reasons. Refund will be after 3 days of receipt of the material.
My money is blocked, my efforts gone waste, my product is no where to be seen. At every stage I kept Amazon informed but no action was taken to set things right.
