Vcare Hair Clinic — Misguided with wrong product

I've visited vcare 7 days ago and they guided me with psoriacare product which I paid arround 15, 000inr, now I revisited the clinic and now they are portrayed different cause and trying to sell another product which costs arround 35, 000.
Regardless of money, the second product is the right solution for me from the beginning.
In that case why did they given me different product at the beginning.
I already started using one of the pack and another pack isn't opened yet. I want to return my package and initiate a refund ASAP.
Very dissatisfied with their service.
