H1B approved but not stamped yet

Experts please help…I filed my H1B through a company called 3i Infotech in 2016 and it got approved 4 months ago and till now they haven’t communicated about visa stamping nor responding to my emails. I am new to this whole H1b process so I don’t understand why they are unwilling for me to go for visa stamping. What do you guys think could be the reason? Is this happening with other companies too, because of recent H1b changes? Is it worth a wait?Luckily they haven’t charged me. Anyone from 3i Infotech here, how has been your experience with this company?

You need projects to go for visa stamping. Some actual real job is necessary. Until your employer gets you one, its not good to go for a stamping.
