Hopeless bus arrival

I've been waiting for A1 bound for DMK airport , and all the bus that passed by me was A2 which is not on the left lane to pick up they just rushed through the troll way gate . It's been 1 and a half hour I've been waiting in front of the ICAO building and all I've noticed are 29 and 510 with no english indication of destination . BAD LUCK FOR THE PEOPLE IN BKK TO HAVE SO POOR TRANSPORTATION.

Dear users, Bangkok Mass Transit Authority acknowledged Send the matter to the relevant authorities to investigate the matter. Please note that the A2 bus travels in a special express route. Will only park passengers in the airport building By not being able to accept passengers according to the bus stop outside the airport building. Update cars 29 and 510 to continue with English text. Please be informed accordingly.
