Flipkart — Product didn't match with description & replacement was cancelled without any refund

Hi,

I had ordered Head & Shoulder shampoo from flipkart application which was coming under an offer where they were offering 1950ml for 500 Rs. On 13th March 2022 my order was placed and on 16th March I received the delivery.

But, unfortunately this was not the same order as I placed . I placed order for 1950 ml and I received only 650 ml product. Moreover this product defective as well, shampoo was leaking from bottle when I unpacked the order.

Immediately I tried to return the product from app but it didn't work giving error as "something went wrong. Please try again later". After 3-4 calls to flipkart customer care they were able to successfully place replacement request for product on 17th March and After some verification the replacement request was approved and placed on 19th March.

It was supposed to be delivered by 25th March but On 25th March I received mail stating that due to logistic issues product is delayed and will definitely be delivered by 1st April 2022. After that I keep getting notifications that my product is shipped (27th March).

On 28th March I suddenly got a mail saying that this order is cancelled due to quality issue and money will be credited in 7-8 days.

Now I don't understand few things :-
1. Replacement order was cancelled due to quality issues. Why was this quality check not performed on first order, that product was delivered to me without any problem ( except the fact that it was not the same product nor in proper condition) .
2. I ordered this product because it seemed that there was some offer going on and I was getting product at low price, now obviously I'm not getting same product at same price.
3. This is clearly not the correct way of handling the customer request if the seller was at fault you should have changed the seller and sent the product from different seller because the product was being manufactured by different company not by seller right ?
4. Even in future if I get some offer and try to order product I need to keep in mind that this order may again get cancelled.
5. Wasn't it responsibility of flipkart to proactively check the seller credibility rather than waiting on customer to suffer and than report an issue ?
