I have to change my 5 stars to 1

The plugin never worked and after the helpdask folks tried to fix it, the plugin failures only got worse, 3 times they by logged into my website and made changes to the plugin but they never got it working. I had to change into another form plugin which is now working and they don’t even have a refund either.
Edit: And apparently you can’t even change the stars or delete your review, this plugin SUCKS!!
