There are more likely reasons they might have cut you off other than "brain rape", specifically 1) They didn't like your code or your forecasting strategy. 2) They didn't like you, didn't trust that you could get it done. 3) They chose a competitors product. 4) They canceled the project. I work for a 50,000+ person company. I do software evals all the time, not source code but still. When their sales people call me, I ignore them. I'm very busy, if I want to buy I'll call you. My group (200+ devs) starts and cancels new projects all the time. No one has time to call every losing vendor and tell them they didn't make the cut, or that we decided not to continue the project.
