Twigmo and Paypal

Hi maybe someone can help on this I have reserched and can not figure out but when active and you checkout on mobil phone the credit card works and check but paypal goes nowhere. I looked in the payments foolder in the addons-twigmo payments and only php file missing is the paypal, where do we get one or how to download this to work

I could do with knowing this too.

I am trying to get support for Twigmo from the CS support team, but they don't seem to ever want to respond.
