Does anyone do Testerz.io???

I barely see anyone post about testerz. Is anyone having trouble getting your amazon review being accepted by them in the last couple days?? For me, they usually accept my reviews, but I reviewed a supplement and couple of days later they denied my review. They then emailed me asking for my amazon invoice for that product that I reviewed. I havent gotten my points yet and I emailed them asking why and whats going on because I also cant see any other products to choose from. They also havent responded to my email.
