that's strange I received auto reply two days later, also IRCC status changed on the same day. which name did you use to raise the webform? the wrong one to match the record?Hmm... if that is the case, I got a response to an enquiry about updating the principal and dependent applicants' names on Feb 16th. But I don't see any updates.. and now we got medical and biometric requests with wrong names on March 1st. Submitted another web form on March 1st, also got an automatic reply on the same day... let's see when will I hear back... it's just frustrating...
EDIT: do you know your visa office? you can send an email with file number.
