Airports Authority of India — Regarding charging 55 rupees for dropping at airport

Address:

Khordha, Odisha, 751020

I booked an uber taxi for airport on 16/03/2017. The taxi was charged 55 rupees for only dropping which ultimately was paid by me. Second thing was that no proper receipt was given. The receipt only mentioned vehicle no 55. Previously I paid rs 20 for the same. Why would I pay for just dropping & if charged, a proper receipt should be given. So look into this matter as it highly inconvenient to throw our hard earned money for this unexplained and unnecessary charging.
