total piece of crap, no sales in 7 days and so much validation in trial version

I have tried to install this tool in my site, I haven’t seen any sale in 6 days. I asked them to check the messenger checkbox, so if someone lands on product detail page, we get the conversion. They told me, it is available in the paid version, if I can not truly evaluate recart, how can I go for the paid version. You only give us 7 days trial and total piece of crap app.
