Why would you call them in the first place? I was actually being facetious in my earlier remarks! Remember the dude who volunteered to return the RTD just because it was valid for more than one year!
I am afraid you somehow assume that there is logic at the INS. A good term of reference: only complain when your interest is being adversely affected by their inaction, ineptitude and disorganization (which is 99% of the time anyway). When they screw up to your advantage, enjoy the fruits of their inaction, ineptitude and disorganization. Trust me, unless you have committed fraud in seeking a benefit, you will not be penalized for their screw ups.
