Not working!!!!

They took my money, but the app doesn't work!!! Don't waste your money on a pointless app!!! You'll only be paying off your credit , but you won't be able to text or call anyone. They're scammers.

Scam

Free trial scam. I tried to sign up for free trial and it was not working and still they charged me $40. I never signed up for the service or used it, still I was charged and apple refuses to refund me.
