I agree that the help line is very unhelpful. They dont know what's going on at the service centers, can't see much else about your case than what you can see and often times are uninformed on the actual process of the visa. I called once because I still hadn't received my NOA2 hardcopy. I told the lady I hadn't gotten it but was informed by Cali (used the RFE trick) that I had been approved and had received the letter from NVC that they had gotten my app and would be sending it out soon. She told me I was wrong, my case couldn't have been approved yet since I was at 3 months after filing, not the 6 they post online. She also told me that K1's dont go through NVC, so I was also mistaken with that.

Always confirm ANYTHING they tell you, as its often wrong or just a restatement of what they post online (which is usually just CYA) I suggest either posting your questions here, make an infopass appt (depending on what you actually need to ask/how damaging it could be) or meet with a lawyer. Either way, dont rely on what the info line tells you!
