The vehicle number is AP16Z-0605 The Ticket price is Rs. 260(Nellore to Tirupati). I gave 500 ruppess, he only gave 200 in return, i asked him about remaining 40. He said, he will give the money at tirupati and i asked him to write 40 number on the backside of the ticket. He refused and told me that, no need to write anything on the ticket and i will remember you. But, when the bus departure at tirupati he scold me so loud and started argument with me. At last, he finally scold me some kind of bad words and gave the money. His behaviour is very very very bad. Please take some behavioral classes for this kind of persons!
