Unexpected issues of 2nd VAC

#1
Guys: I received the email notifying me to pay the 2nd VAC today. However, in the email, it is said the applicant who is liable to pay the charge is my daughter, but she is 2 years old. I'd expect the applicant to be my wife. So any possible explanations here? Should I a) go ahead finishing the payment? or b) contact the CO for an explanation or an updated email (kinda worrying about another two-month waiting). c) wait for a further email asking for the payment for my wife? (if so, what should I do with this one?) Thank you

You should get this clarified with your CO. Send the an email mentioning that the VAC2 should be for your wife and not the child. It is better they correct the requirement and resend it to you. This done prior to the payment would avoid any confusions at later stage
