Toothsi aligners - Non refund of booking Amount

After watching an ad for free consultation by tootshi, I called them up for my dental checkup. After dental check up, their representative gave me an exorbitant price estimate of Rs. *****/-for dental alignment work. However, they also give you a lucrative offer that if you book now on the spot with a booking amount of Rs. *****/-, the same price will be reduced to ***** from *****. In the same manner they took booking money from me also and told that if I change up my mind later, they would refund the whole amount Now that I had made up my mind and decided not to go for their programe I contacted their representative and informed her to cancel my booking. But after constant for more than * month, now she is giving me reference of toothsi policy and telling that refund is not applicable to me which had never been mentioned to me earlier by any of the toothsi representatives.
