Make My Trip — overcharging by make my trip no gst invoice

Hi, this time i have been overcharged for hotel approx rs. 980/- per day as the make my trip has bifurcated the room with breakfast and without break fast and also prices having rs. 980/- day more than tariff in the hotel bills issued by both hotel and make my trip is less than the amount paid each other saying you will receive invoice from hotel/make my trip/ please call hotel before making any booking on make my trip yo avoid overcharging / misrepresentation of prices/inflated prices. My colleagues also stayed for the same period hotel premium tariff was rs. 2700 including gst and complementary breakfast. But make my trip charged rs. 3644/- per day in total as overcharged their website is so designed that price changes from rs. 2430 to rs. 3890 per second and they are saying they have contract with hotels to charge the amount on their will to cheat the customers daily/ per second basis. As against previous bookings (Approx paid 90000/- for two booking) such act is wrong.
