Today is really a very bad day for me. In the middle of the Survey the power went off. i really frustrated. Just 7 or 8 questions were away from completion. What to do now.? Can Clixsense consider such situations.? Any way for this?

ClixSense does not create surveys.
ClixSense does not own surveys.

The world may end in a moment. ClixSense cannot prevent the world ending.

It's not anyone's fault that your power went off other than perhaps, the power company.
You could contact the power company and tell them they owe you money for your incomplete survey.

I hope tomorrow is such a great day for you that you'll forget about your misfortune! Hang in there! Things can only get better!

We all have a bad day here and there, but the good will outweigh the bad. Make the big bucks!

Why don´t you use back-up power supply?
1 hour supply for all devices together you need to do this work is more than enough to complete and turn your PC off.
