I am a technical support engineer.
My mother tongue is not English, I still write and speak with a lot of mistakes, constantly improving my English skill, please do not judge me strictly ;)
In my job I have to communicate with people around the world from Alaska to New Zealand and not all of them speak English clear and fluently. Sometimes it's really hard to understand them, sometimes it's just impossible. Even they think they speak English very clear and without mistakes, but it's not (unfortunately).
I decided to start learn another languages in order to communicate with clients in their languages to make them and me feel comfortable.
Thus, I'd like to get known is there any vocabulary for techsupport or some kind of best practices, e.g. how to say "Hello, you've reached technical support, how can I help you", "please describe the issue you faced in detail" and so on.
Actually I have to know not only these words but much more, however I'd like to take a start in a right way.
