Everybody has had bad experiences with call centers... it is actually quite an entertaining lunch topic with friends, colleagues and clients.
But this Comcast example deserves the gold medal for the worst customer empathy example...
Ever arrived at the checkout of your supermarket to notice a problem with a product you picked up from the shelf? A damaged pack, rotten fruit/vegetable in a bag, an expired date, etc.
It just happened I had a similar problem with some rotten oranges in a bag in two different stores in the last few months that nicely illustrates a hit and miss of customer empathy...
