Actually timing is 6.30 pm ist, but bus reaches boarding point on 7.30 ist..
Its more then 1 hour delay... There is no response from operator side,...
No bus number,, no one is in office... No one attend the call...

Since i'm going to aboard.. I book the branded kpn bus... But its totally disappointment for the service... I will rate zero... Since my flight.. Now decided to start on car... I need refund for this trouble n explanation...
