Today I had to transfer the call to a colleague, and he was busy so i transfered to another just to say to pass the information that the important client is waiting on the line. My boss yelled at me because I've done that and pointed that i'm doing it every time. Can somebody please tell me what the f**k am i doing wrong?!?!
just 3 days 'till my salary is payed and i'm getting away form here..It's been enough
