DIMTS — balance amount after ticket I left out

Tomorrow (05.01.2020) at 01:15pm, i picked up cluster bus of route 728 from dwarka sector-6 & 7 crossing. For 15 rs ticket i gave rs.105 to conductor. Then bus got breakdown at dhaulakuan and i forget to take my money back from conductor and conductor also did not write balance amount on back of ticket. Shall i get my rs.90 back. Please help, if someone can do.
