Service is a rip off - avoid at all cost

I signed up for the free trial and extended it for a one week subscription. When I logged into the system it provided me with a button to utilize my subscription but that automatically converted me to an annual subscription. When I clicked the link to contact the developer it brings up an email screen with a blank to Line: clearly they don’t want to be contacted. The next thing I noticed was that it had also charged a second weekly Subscription. (Which got refunded when I requested a refund through Apple on the annual sub.) I filed complaints with both the credit card and Apple but I can’t contact the vendor directly. Sure seems like a scam to me. Avoid at all cost
