Participation in Mobile contest

I've been participated in a contest at Idea network organised by third party. The prizes are - Audi, Harley Davidson bike, Mobile Phone, recharges etc. The contest consisting of 3000 questions and charges are Rs.2/- per answer. I played the contest from two mobile numbers which costs Rs.12000/- (6000x2). There are some recording mistakes in answers of the questions asked for in the contest. When the mistakes were reported to the contest organising company and asked for bonus points for fill up the loss, they denied to do so referring the terms & conditions of the contest "The Organizer shall not be responsible for any claims arising out of any failure(s) which is beyond the reasonable control of the Organizer. Without limiting the generality of the foregoing, the Organizer shall not be responsible for any claims arising out of technical failures before, during or after the completion of the Challenge including but not limited to any technical failures in the mobile connectivity, delay in sending or receiving the SMS for participating in the Challenge, delay in time recorded or taken for answering a question during the tie-breaker process, any action that has been initiated, actioned or completed through his/her mobile phones, failure of servers or the failure to provide the correct score updates or any failures arising out of technical snags or resultant inability of the listener for participation. Organizer shall neither make any alteration in the score/data/records for the challenge played by the subscriber nor grant any point for the right answered question or extra benefit for the right answered question will be granted to subscriber" There are problems in 24 questions identified & reported while playing from first number and 4 questions identified & reported while playing from 2nd number. It has come to my notice that the company has considered the same situation and award him full marks of the reported errors with a Harley bike but my cases were not considered for getting bonus marks and I was found suitable only for 01 mobile phone. As per contest Terms and Conditions it is subject to Indian law and the exclusive jurisdiction of the Courts in Mumbai. I still feel that I must be get Audi prize according to my performance based on 100% correctness in the least time. Idea has nothing to do when the petitions were filed to them. Kindly guide me what & how to get my claim for Audi. Please also suggest the name of suitable lawyer who can handle my case effectively so that I must be get my prize.
