My experience with TS.

He/She might be good in their service but won't allow any question asked.

Even if you provide free service I'll ask the same thing, how to verify the VISA??

Though it might be annoying to TS, it can just said pls check the link provided or something rather then act all high & mighty saying wont service ppl that have no faith in them.

Hello...u pm out of the blue, of cos any sane person will ask question.
