All telephone numbers are busy all time

Location/place: Bangalore

Name of company/service: Ananth Gas Agency

This agency is giving very poor service. Never you can reach them on phone though they have given some 5-6 numbers but all of them will be busy all the time and even if by any luck any number rings nobody picks the phone. I dont know how all the numbers can be busy all the time. Please take some action against them. Gas cyclinder delivery is also delayed.
