Euromotiv review for Easy Watermarks | Engage

The app advertised that they can do up to 350k products, i was a little over so they told me the app wouldn't work and they would give a refund. I removed about 30k products falling under 320k products. Then they said i need to pay them before i can use the app (they blocked me from using the app). Now i message support and they tell me to read the previous messages. They are not professional, they for some reason don't want me to use their app because maybe its overloading it. Please don't advertise something you cant handle.
