I don't know whether it's lack of training or deliberate tactic to get people off the phone - a lot of USCIS tier 1 agents would tell you incorrect information.
I'd imagine if you give them any clue such as "should I cancel payment"?, they'd reply "yes". If you asked them whether you should leave the US, they'd advise you to.
My theory is they're underpaid, undertrained and have a goal of answering XX number of calls an hour. If they answer lower number they get penalized. I cannot explain otherwise why so many times their advise hurt VJ members.
