Keragain — Defective product received

Hello,
This is Dr Asha Kumawat wants to bring your attention towards the poor quality of KeraGain Hair color Shampoo. I had purchased the same with Batch no. 021421KHCB and also with the valid expiry date (01/2024) was defective as it is said the shampoo should come out from both the nozzles but I emptied half of my bottle and still it was'nt which gave me unaffected results with no change at all.
I would really not appreciate the quality and the assurance you give about the product of being 100% effective. I had regret wasting money on such product.
So, Here I request you to compensate the loss or justify the expense at your earliest convenience.
Thankyou.
