Rto India — refund for driving license test

Address:

New Delhi, Delhi, 110015

I went to rto office situated in raja garden for my ll - dl10 /0006896/2019 on 15/01/2020 but when i arrived the said that i can't give test because my number plate is corrosive which was totally incorrect they said get your refund and don't come with this scooty again. Serious unprofessionalism from the test takers.
