CC Bill Legit or not

Hello

I am considering adding a payment system to my website and am looking at the CC Bills plugin which is free to use.
I also searched the internet for cc bill to see if i can find any information about.

I saw on Thrustpilot a lot of bad reviews about CC Bill. and i am confused to add it or not

My question is: Does anyone use CC Bill as payment system in Flynax Themes?
and if you use it do you have any advice, i would be very happy if you share your experience about using it.

thanks
