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. *****, 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 within ** days from the date of cancellation. 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 *two month, now she is giving me reference of toothsi policy l will be not be refunded any money which had never been mentioned to me earlier by any of the toothsi representatives.
