There were so many number of threads here, when people wrongly entered PAN (or were trying to fool PP) before PP implemented this change option and they kept on asking about how to change the PAN. Now when that option is here, none of those people is around to tell whether he/she is able to change it successfully using this option! This speaks LOUD of the mean-ness/selfishness many people show in forum, when actually its the time to help!
