Naturals — Denied service after selling membership

Customer service at Hyderabad-Kokapet Natural branch is more than just pathetic. I was denied service by the hardresser on hair dandruff grounds. Being an hair care professionals, instead of providing solutions to customer they simply denied service and the store manager/owner showed no intention to intervene and rectify the situation. I was sold a membership in my last visit and now was simply denied service. I think this is not fair, I am at a loss of the membership fees and they are not willing to provide any service or refund my membership fees as well. I want to raise this concern and hope to get a resolution and fair compensation from the company for such humiliation and inconvenience
