National Highways Authority Of India [NHAI] — Devanahalli Toll plaza charged twice on same day of travel

Hi
i need to complaint on Devanahalli toll plaze as they deducting toll charge multiple times on same day of travel. on May 23rd when i was travelling from bangalore to Anantpur i was charged Rs 105 around 11.51 AM, and i returned back to bangalore city and crossed the same Devanahalli toll plaza on same day that is 23rd May around 01.07 PM with price of Rs 55, after finishing my work, again i satrted my travel from bangalore to ananthpur on same day that is 23rd of may and crossed Devanahalli toll around 03.05 PM again they deducted amount of Rs 105 . why this toll is charging multiple times on the same day, it has to be free for the same toll on the same day. what kind of fraud they are doing. this is really insane,
