Hans Travels — Price hike without any reason

I wanted to book sleeper bus ticket from this co.'s site for Bhopal- lucknow route in april. But when checked the price, it was 300 rupees higher than normal fare. When asked in customer care for the valid reason there was no answer for it.
In march the fare was 1200 and in april it was 1500.
Please take strict action against these kind of problems consumer has to face without any reasons.
I have attached the site screenshots for both months in my complaint.
