I tried the free version of dfnder, have never tried the premium version..not even the free trial..I only noticed that I was billed $23 and some odd cents after their bill was denied while going through my email..in fact I had already uninstalled it from my phone…how is it that I’m owing this money when I don’t have the app any longer..this seems like a scam to me..I’m trying to resolve this issue with you first before I file a report to Google. Can you help me with this issue please..
