Yes, I did sent a webform and email to New Delhi IRCC for the reconsideration request with required documents and it's been 30+ days. Unfortunately, I didn't receive any response from them except for the automated email.
I contacted New Delhi IRCC agent via phone call to enquire about my request, the agent was of no use as she suggested me to send a webform like she told me earlier.
Still waiting for their response. Hopefully, this time they'll look into my file carefully for the reconsideration and approve my WP Extension.
