RTO India — learning license slot booking not done.

Address:

RTO DHANBAD (JH10), Dhanbad, Jharkhand, 826001

I am trying to book a slot for learners license for 15days now. But everytime it shows "slots not available for next 7 days" rather when i go for slot availability check, it shows available slots and it also gets decreased with time (Meaning someone is able to book) but i never get a chance to book. I log in to my account and it shows an error message saying the above mentioned thing. Please help! Its really harassing and disturbing. Dhanbad, jharkhand (Rto - jh10)
