http://theoatmeal.com/comics/customer_service First hand experience today. I swear this about exactly sums up what happened to me and my mother today when we needed to fix our internet.
Yeah, I've got experience with that too. Tried to change my flight to another day, called the number they gave on KLM's website, and then after five minutes on hold they redirected me three times. Then the lady who could potentially help me couldn't get her computer to work, so I wait for another five minutes until she tells me that I can't change the flight, and apparently the tickets sold to me weren't completely eligible and I should've flown out a month ago. So yeah, I hate calling.
Well, I've never had THAT much trouble with tech support, but I do hate it when they play the waiting music in horrendous quality, and then make you listen to stupid advertisements. Heck even the music from the old Betty Boop cartoons have better quality then what tech support gives you!
