For almost two years I and two coworkers were involved in developing a blockchain app for a fairly big FinTech company. We did everything and I mean EVERYTHING they asked, a lot of which weren't even mentioned in the contract. Now after two years they said that they're not satisfied with the app! I mean we implemented EVERYTHING that was mentioned in the contract. They refused to pay us and now we have to follow legal procedures. Last Tuesday we had a meeting with the bastards. It was a very hard pill to swallow when they said that we didn't implement what they wanted. I even raised my voice once or twice because I was very angry and frustrated at the same time.
