Goibibo.com — goibibo.com didn't inform the cancellation of Bus

Address:

Bangalore, Karnataka

I have booked ticket in Shameem travels from Bangalore to Hyderabad on Sept 16th, 2013 for travel on 31st October 2013 with boarding point as Hebbal. The departure time mentioned was 10.15pm. I started from my place at 8pm and reached boarding point by 9.45pm. The bus did turn up till 10.25pm and gave call to the operator of Shameem travels. He said Bus just left to Majestic and it will take half and hour more. The bus didn't come till 11pm and gave call to shameem again at 11.06pm. He said it will take 15mins more. The bus came at 11.20pm and when I show my ticket he says "YOUR BUS GOT CANCELLED" I was like you didn't inform me. He said the website from which you booked the ticket should inform you.Call them and ask for alternative. I requested him to wait until I call goibibo.com. He said "NO SEATS AVAILABLE AND LEFT". I called goibibo at 11.21pm and the operator took long time to understand my issue and she was like "YOU SHOULD HAVE INFORMED US 2HOURS BEFORE" I was shocked to hear that and said "YOU'RE THE GUYS WHO'RE SUPPOSED TO INFORM ME". She took shameem operator's contact no from me and put me on hold for long and came back with news saying "SORRY FOR INCONVENIENCE, NO ALTERNATIVES, WE'LL GIVE U FULL REFUND, TAKE PUBLIC TRANSPORT AND GO HOME" This call went for 15mins and it was 11.40pm already. By the time I reach my bus stop to take bus for my route it was 12mid night. Being an alone girl it was such an inconvenience to get back as there was no public transport and I took a pooled car which wasn't safety at all at that point of time. I reached home by 1am. I am really angry with what has happened and want to sue this goibibo.com ppl. How to do that ?
