CSMIA has crazy exchange rates

Went to exchange 5500 INR to USD and the rate he gave me was 5500 INR ~ 49.2$. The actual rate today is 64-65$ for 5500 INR and they are giving me almost 15$ less. Sheesh.

Update: I exchanged my INR at Changi and got 63 dollars. What is wrong with CSMIA? Scamming people?
