Complaint against online Company for their wrongful practice.

Sir, I am currently working with an online company named adindiatube.com, they pays for viewing ads on hourly base. The condition for payment is : No. Of hours work done in a month upon total no. Of days. The result would be considered as the average payment hours. From 1st may to 18th may my average was 9.9 hours daily and with that average estimate my monthly income would be ₹28000. But on 18th may the site got slow due to company's internal system error. Now the daily average that was 10 hours daily fall to 5-6 hours daily. They said the system would be repaired in 2-3 days after that we can recover by doing 11 to 12 hours daily. But it didn't got repaired till now. On 26th may 2017 they shut down the entire site for repair which was back online on 28th may evening around 6pm. My average fall from 10 hours to 9, then 8 and now it's 7 hour daily. Which would pay me ₹11000 now. I complained this to the company and they said that it's system fault we can't do anything. So what to do?
