Toluna Surveys

Again another bad experience with Toluna survey. I was in the middle of answering the survey and then there was error in loading the page.

I tried everything to go back to the survey but to no avail.
This would be understandable if of all the surveys I have answered or participated with have the same problem. But I have experienced this only with Toluna.

It's a really really bad bad experience. Honestly, I don't trust Toluna anymore and I've been questoning its legitimacy.
