Bangalore Metropolitan Transport Corporation [BMTC] — ticket was provided for lesser amount

Address:

560101

I boarded the bus from silk board (Under flyover) and asked for ticket to iblur which is rs.40 he collected the amount and immediately asked me to move in.
When i asked for ticket he said "move in i ll give" after that 3 times i asked he said that he ll give with irritation tone.
Finally one station previous to iblur stop when i asked he gave 10 rs ticket saying station is closed cant give for 40rs. What kind of service is this? Is this fine for me or incentive to bus conductor.?

Regarding bus number, confused again it had 2 numbers inside and outside different number is it possible in a government bus to have like this.
Inside - ka01 fa1751
Outside - ka01 f4528.

Attached my ticket...

If this is not the the proper mail id please provide me the mail id to raise the complaint.
