NEGATIVE REVIEWS NEVER LIE. You know that!
I installed the app to my client's store from the very beginning, 2-3 years ago, when they had only a few customers. It worked like a trash, but I was patient. Claudia - the CEO - asked me for ideas to improve the app, and he provided FREE FOR LIFE to my account. Now the app has changed a lot, and a lot of those change were the ideas I shared with them. About a year ago, suddenly his staffs did not give me full access to the app --> Claudiu apologized that nobody in his team knows that special offer Free For Life, they fixed it and gave me full access again. AND NOW, SUDDENLY THAT THING HAPPENED AGAIN! They removed the feature which I was able to use from the beginning, and ask me to pay to use it. THEY BROKE THEIR PROMISE, AGAIN AND AGAIN! They made me feel wrong with my client because I promised my client that he can use the app FREE FOR LIFE which Claudiu the CEO told me. They stole my ideas, they promised good things, they beg me to remove the negative review, and when they get some more customers, they broke their promise. SUCH A HORRIBLE AND UNTRUSTABLE COMPANY! SHAME ON YOU GUYS, EVEN CANNOT KEEP A SIMPLE PROMISE! ****************************************************
UPDATED AFTER THE APP'S RESPONSE

Blackmail?? Sounds funny PROMISE BREAKER! No worry, I no longer want that feature which you called "premium" while it was promised to be FREE FOR LIFE for my account :)) I have all photos, emails as proofs of what you Claudiu promised me, and I don't mind if anyone asks me for those proofs, just email me drc.supply@gmail.com . I'm telling the truth so I'm not afraid of that. Shame on you guys!
One thing I forgot to mention: my client (the cosmetic company) used to blame me because they received a lot of spam emails from you guys advertising for the service, even without a Unsubscribe button. That's annoying, stop it!
