Sabka Dentist — proper quotation not provided

I booked Root canal Treatment Which costed arround 5000 some discounts were going so it came to 3850/- And 6000 For bracket. This was the Quotation given and I paid for root canal. Full payment done. But for 2nd sitting they asked me for payment of filling and said filling will cost extra. Even my ortho treatment hasnt completed yet its been 4 long years. I contacted customer care who did nothing about this. Not to go to this Clinic ever.
