I know this is an old thread and pardon my rant, but today I was told by a Verizon employee that Wifi networks with WPA2 encryption are not secure and the only way to have a secure network is to buy an unlimited plan through Verizon lol.
The biggest problem with customer service (in general) these days is that the reps are people who fall into one of the categories:
1) Decent people who are good at customer service, and know how to buff up their knowledge to fill gaps, and admit that they may not know everything about what they are trying to sell/support.
2) Decent people who may decent at customer service, but don't know enough about the field they are selling/supporting and are trying to put on an air that they do.
3) People who simply cannot find work elsewhere and trying to make ends meet, but are expected to know something about the field because their job depends on it.
A lot more people wind up in #2 and #3 than there should be to get good service. People in #1 are good to work with, seem to learn from their experience, and you don't mind talking with them while you shop. #2 are okay some of the time, but if you hit an area they don't know, watch out. #3... well, stay clear of these folks. Sounds like you found yourself a #3.
And the big problem is that the people in #1 get better jobs. These are the folks who can sell large orders to companies that pull in hundreds of thousands to millions of dollars at a time. Or if they know tech, they go into the tech industry (especially with a shortage of good programmers these days). Odds are good that customer service reps won't know one TLA from another.
