same situation. got no response for themHey there, I am in the same position as you. I withdrew and sent an email to OINP just 4 days after I submitted my application.
It has been 2 weeks and I got no reply to the email, their helpline also goes straight to the voice message.
Can you please tell me how much time it took to get a reply to your email?
And did they give you a timeline? I got ITA issued as well but, I need the OINP fee refunded to cover the costs for the Express Entry-FSW ITA, so any guidance would be greatly appreciated.
