My issue is the courier ecom express denying doorstep delivery
The order is reached at ecoms nearest center 'perambra' on 7th october. The next day (8th october) 12.43 pm i received a fake-out for delivery message and within 10 minutes (12.54 pm) received another message showed delivery attempted and the customer is unavailable. Are you kidding me? It was a fake delivery attempt. I contacted amazon customer care through chat he said to me that order will deliver on 12th october the estimated delivery date.

The next day (9th october) i received a flipkart order from ecom express to the same address which was reached on the 9th morning at the same delivery center. (Awb no [protected]). The delivery boy provided a doorstep delivery without any issues. Again i contacted amazon support to discuss the discrimination (Flipkart order is delivered and amazon not). But as usual, the customer executive said to me that the order will be delivered on 12th october.

On 10th october again received an order from flipkart through ecom express to the same address. (Awb no [protected]) and i contacted amazon and the executive said to me that order will be delivered on 12th october. After these incidents, i thought there are some issues with amazon and ecom express.

On 11th october i received a fake-out for delivery message at 2.53 pm and delivery attempted message at 4.35 pm. Again i contacted amazon got the same false promise that "product will be delivered on 12th october".
But i didn't receive the product on 12th october. but i received another amazon order (Same account same address and the same courier ecom express!!!) order #[protected]Tracking id: [protected]) please check it. (Provided doorstep delivery!!!)
Now i realized that something is wrong.
I asked about this issue to the delivery person who delivered the above order.
He said to me that the order package is too heavy for him!!! (2kg of detergent, 150 g phone, and a few gram headphone). So they will not deliver it. He asked me if you need the product then you want to collect it from the delivery center. Very bad service.
The delivery center is around 30 km away from my home. It is very difficult to collect it from there.
He added that they will attempt one more fake delivery attempt and they will return the product. And the previous two attempts were also fake.
Again i contacted amazon chat support, poor service, no hope to solve this issue.
I already lost a lot of my time.
Totally disappointed.
So i request you to solve my issue.
Please escalate this issue to a higher authority.
