@Abhishek.Pandey Not question foe me, there might be technical reason, may not applied at cut off/maximum price, difference in name, etc. First you need to contact your broker and check all your details. Difference in Bank and Demat account. Need to check immediately before applying other IPO. Your problem will definitely be solved.
@Sunil Anand Whenever no trading is done for one year in your account the trading account is blocked. One need to take necessary action to unblock account. One can't trade but demat account is never blocked for the reason of not trading for a year. Whenever one applies and get allotment, the shares will be credited in one's demat account. Credit will never be denied exceptfor specisl reason. I have personal experience and just confirmed from the broker. Posting this message thereafter.
Trading is blocked and not the demat account for non operating for one year.
Even if I am still incorrect, please correct me.
