Time wasting app

I wasted my time in March answering multiple number of surveys and in most surveys, especially the ones with most points, I didn't receive my points. I contacted their help centre and they told me not to worry. They will fix everything by month end. I contacted them on the 1st of April, they told me that they are conducting an investigation. Since then when ever I try to contact them, they don't reply. I still haven't received my missing points from last month. It's a time wasting app.
