How to engage in VISA
It is only for telephone correspondence,
I was just tied up just asking a question.
It was extremely painful to think that information that I had never heard was thrown in frustrated from the beginning and I was throwing rough words over the telephone bill and time.
Is it better to hold as much as possible to drag the personal irritation to the next response as it is before work?

Either way, I understood well only that it is not a category of customer service in the first place.
