Prepaid Taxi At Howrah — taking more money and not returning the change

Address:

178/1kamalpark ,Aditi apartment, birati, kamalpark, birati, Kolkata, West Bengal, 700051

I booked a taxi from howrah prepaid section. Our bill is 331.80. We gave him 535 but he did not return the change. Is possible please return the money as soon as possible. This problem just not for us only they did the same thing with other customer also. They did not called the customer to give the change if the customer forget to take the money. How irresponsible they are. Strictly take an action against this complain.
