Disha Eye Hospitals — no customer service and very rude behaviour

Address: North 24 Parganas, West Bengal

For disha there is no customer service available. The numbers shared in the prescripion and internet is of no use. Even face to face behaviour of the disha members are pathetic. For mediclaim the insurance company is waiting for a document for 3 days but disha is not responding at all. So everytime the custoners will go through this mental harrasment?? Is there any possiblity to take proper steps and to let them kmow how to behave or assist with the patients and their families?
