@Nothing New also check if you have applied at lower price band by any chance, and selected correct demat account while asba application in hdfc, if you are very sure about every detail correctly applied (cut off / higher price band, correct demat acc, pan, demat, bank acc name matches etc.), then the issue might be with hdfc, in this case, you can claim lost oppurtunity cost from them, since mankind retail is 100% allotment, so, whatever the difference (only if profit) on pre-open (preopen price - 1080rs) can be admissible claim here.
In the past many banks settled in this way, I am very sure about RBL one such issue... Hence try this way... contact customer care for this, before that take confirmation email from registrar that the application is not submitted with your pan number
