Replying to [Mickey Mouse]:
I don't like making phonecalls only if it's urgent.
Because, there's one important thing: the customers must have inquiried many suppliers and they may even CANNOT remember or DO NOT know which company you are from and who are you.
It's a little embarrassed for both of us.
In this situation, making phone calls are just useless.
And if it's really urgent for me to get responce from the customers, I will call them and I'm sure at that time, we've communicate with each other for many times and of course we've known each other.
