Akosha.com — wella elements shampoo

I purchased wella elements shampoo from amazon.in (1000ml) worth rs. 1800, the product is totally fake and has damaged my hair. I called amazon customer service, they told me to contact wella company. I called wella company, they said that they do not sell on amazon.in now, hence the product would be fake only. Now neither amazon nor wella is helping me.
