I could tell you stories from dealing with customer complaints - but assorted NDA's prevent that. But I will say this - the most heated, hateful complaints almost never come from the so-called '1%ers' - they come from welfare kings and queens who demand free crap - and threaten to sue if they don't get free crap.
Two stories - sanitized to protect the customers and the companies involved.
A ) Company, you used to give me free bonus vouchers every month through the mail, why did you stop ?
-Well, you are only entitled to one voucher, and it was our mistake. We are however going to honor all of the vouchers we sent.
-Oh yeah ? well guess what, Company.. those vouchers are now considered part of my income, and if I don't get one now, Ima gonna sue.
B ) Company, why are you no longer providing me goods and services ?
-It seems here you haven't paid for the goods and services you have received, so we had no choice but to suspend further delivery.
-Oh yeah ? well, I'm disabled, and you are in violation of the Americans with Disabilities act, and now Ima gonna sue...
The substance of both of these are true, I just did my best to remove any identifiable details.
