Poor/rude telepnonic customer service

When you phone the financial services department, you spend 5 minutes listening to all the different options, which none is the reason for your call. Then you choose one, just to get to speak to someone. When someone answers, but don't want to help you, because you ask an unrelated question, they hang up without saying anything. 10 minutez of your time and unnecessary airtime spent on an absolute useless phone call.
