I do tech support in Apple products. Some of my clients are female who moan about everything. I get a call and its a bitch fest about things not working. ADSL being the latest, even after I tell her the problem is with her ADSL service provider I get nagged as to this is messing up her day ect. It's driving me nuts after having joined TRP to have to listen to the bitching (I know, Meta since I'm bitching here).

My question is how to handle the bitching in a professional way without losing clients.
