We got this same letter today as well! I paid a lump sum of $1390 when we submitted our application ($255 for OWP + $1050 for PR/Spouse Sponsorship + $85 for Biometrics), but the receipt of course doesn't show the breakdown. Now my partner (the applicant) is worried by this letter. He doesn't think we should just ignore it and that I should submit an enquiry clarifying our payment through the link. But I don't want to ignore the instructions to "ignore this letter if you have already paid". Anyone know if we are safe to ignore it?Just received biometrics fee reminder email. I guess now i atleast know that they have really received My application
