What happens to investors' money if Jio allots zero or more lots?

Jio Platforms' IPO was subscribed over 22 times, making allotment uncertain for investors. If no lot is allotted, the blocked amount will be released, while one lot means ₹13,428 will be debited. Each lot comprises 12 shares, priced at ₹1,119 each. Multiple lots are unlikely given the heavy subscription, though retail investors can apply for up to 14 lots.
