@CA. Mumbai I feeling so bad to read your post. I think you had not gone through posts here in this IPO. Many members were against this IPO. GMP was not at all. Even in my post, I told that not going to apply even if I have funds. Done is done. When there was no good subscription figures, it was better to avoid or applied in other categories. Big amount likely to be blocked. You are only the best judge to take further decision.
THIS IS THE TIME WHEN WE LEARN A LOT.
Never repent, but learn by mistakes.
Hope that listing doesn't go bad and you need not get any losses. Positive listing may also be possible even for a rupee or two or more. Nothing certain in Share Market.
Wish you all the best.
