Review Service not good

Cataract operation was done for my father on 27th Sep 2018 and ******** was charged for his operation including Lens. And we have been told to come after one month. Meanwhile my father felt some issues in his eye and he again visited to the same hospital and he has been told that again you need to get a slip of 5000 and you need to come after 2 months as the layer in again need to clean and only than after they will give spectacles. We were not been informed about the extra cost earlier. Perhaps this is the business of the so called Aankha hospital.
