India Post — Harassment by India Post employee

I've booked a speed post under India Post with tracking ID :EU[protected]IN. I'm constantly checking the same but it's been three days since I posted that and despite being speedpost. It hasn't travelled 50 kms from the booked post office. I went on to post office in Shipra and one of the person there mentally harrased me by repetitvely telling me post is wrong and told me to re-check the number and despite showing him 4-5 times he went on saying "bhai phone pe dekh le hm free ni bethe yha" and wasted my 30 minutes only to tell later that mein ni krunga.

Despite, Complaining to toll free number and registering on india post. My parcel is not moving at all. It's still stuck in Delhi. I've important documents in that and if it'll not reach before 9th. it'll be of no use. My bank will cancel my application. Kindly, Please help. This is impacting my mental health
