LOL. Most customer service people I deal with have such a heavy accent it is a real chore to ferret out what the hell they're saying. There are a few who speak well enough, but they've got an attitude like they get a bonus for pissing you off.
I remember asking one rude young man if I could speak to his supervisor, only to have him hang up on me.
I like to tell them that I'm recording them. That typically unnerves them....some clean up their act and speak more clearly and less like a teenager
with an attitude and a mouth full of chewing gum, and others rush to get their supervisor, no doubt because they want the sup to be taken down with
them if they get in trouble.
