Birth date mistake by NVC

[Alkath27 0]

Called nvc to check on k1 status...I've already check it on ceac website with a case # but nvc said that they can't give me a status update because I'm giving them the wrong birthdate of my fiance(benificiary) which I double check it with the I29f I sent and it's the right birthdate so nvc was saying that they prolly input the wrong birthdate on they're system...now they want me to send my fiancé passport to correct her birtdate....my question is why can't they correct it themselves coZ they're the one who input the wrong date and shouldn't they check my i29f form from uscis which I check it a million times and I am giving them the right birthdate same as the one on i29f.

just do as they say,they also had my fiancés wrong date of birth but after we sent to them a scanned passport,they made the corrections and got back to us in a little less than two weeks with the case number and status update!
