Inadequate training. You can't rely on any help from your supervisor. The computer system you work with freezes and crashes constantly, so phone calls that should take 15-20 minutes sometimes take over an hour. It is very hard to give excellent customer service if you have computer issues every day. If you go to IT with an issue and it takes too long, they might not let you finish the rest of your day. Also if your computer breaks and you have to wait for them to send you a new one, you don't get paid for those days you are not working, even though it is not your fault.
