Hello, I’ve been experiencing an issue with the Quebec QST Form FP-2506-V that is preventing me from submitting my application. When I attempt to update my TQ number, I receive the error message: “The Tax ID entered already exists.” This contradicts the note on the form stating: “You can return to this form and update any numbers after clicking Submit.” Steps I’ve Taken So Far: Opened two cases with Apple Support (over three weeks ago). No response. Contacted Developer Support via email and phone – Unfortunately, they were unable to make the necessary corrections. Tried using the official contact form again – No success in getting a response or resolution. Emailed canada_tax(at)apple.com – Even though this email is meant for users outside of Canada, I reached out in the hope that someone could assist. At this point, I am completely stuck, as I cannot move forward with my application submission until this issue is resolved. Has anyone else encountered a similar problem? Is there another way to escalate this within Apple to get proper support? Any help or suggestions would be greatly appreciated! Thanks,
