It's a bit sad to hear this.
But normally if they do not have any doubt on credebility of your employer then they'll send passport with visa stamped in it.
But, still i would say do not loose any hope.
Sometime they check your employer's credibilities in detail which is called Admin processing.
So, as soon as they finish admin processing they'll get back to you(asking for passport) to get visa stamped.
So hopefully it should be done in a month!!
All the best.
Keep me posted
