Yes, they do answer them, but its hard to predict the response time, and also the usefulness of the responses. I sent an email to info@pbec inquiring about my case status. I got a response today which is pretty much the same screenshot I got for the H1B 7th year extension. It has an additional case status field, but for my case this field also says TR (i thought that was processing type).Thanks for the info. But do they answer those emails at all? Anyone tried?
