I was robbed!!

I recently got this app a week ago and it was working fine seemed pretty good, Until it said I ran out of data and needed to purchase a subscription so I did I got the 1 year subscription which they charged me $30.86 for. I was really upset to find even with the subscription it still tells me Im out of data and need a subscription and I cant use any apps or get on the Internet with the vpn connected, Ive tried going into my account and it kicks me out or says the info is wrong when I know its not Ive even changed my password but it still wont let me in my account!! This was a complete waste of money and Im extremely unhappy about it!
