Bought this in 1/15 and now it won’t let me synch without buying again

Purchased the full version of this app in January 2015 and used it to synch about a thousand contacts.

Today, I downloaded the Previoulsy paid for) app to my new iPhone, logged in to my Google account and started to synch my contacts. Lo and behold a notice popped up saying I could only synch 40 contacts and did I want to buy the full version of the program. Lovely, eh?

Unfortunately, I deleted all of my contacts out of iCloud before starting a one way synch from my Google account since I didn’t want to risk the possibility of a two way synch screwing up my Google contacts database. Now I have no contacts on my iPhone unless I buy the program again or Support responds to email to tell me how they can fix this? I feel like I am being defrauded….
