Airtel — my number ported to postpaid instead of prepaid, despite of lots of request

Address: 496001

Website: airtel

My name is sumit kumar, i use to live in raigarh chattisgarh. Back on 10th august i got a call from airtel executive asking me to port my number to airtel and told about the new offers, i got convinced and gave him the required documents and details on whatsapp, she asked me i want to port in postpaid or prepaid, i said prepaid.

After 2 days i got a call from raipur, he said he is going to verify my address as i applied for a airtel postpaid sim, i made him clear that i applied for prepaid.
I call back to the girl to whom i gave the details and briefed her that i got a call for address varification, she said "sir by mistake aapka postpaid me process ho gaya hai postpaid le lo"
I clearly denied and told her to cancel the process, she said ok as address varification nahi hua hai to process khud se cancel ho jayega.

And after 2 days i got msg from airtel that my request has been processed and my number will be ported, again i called her and she said sir process v ho gaya hai.. Sorry.

And my number got off!!!

I use to live in raigarh which is 250kms away from raipur, she never told me that she is calling from raipur,

After trying a lot i never got a chance to speak with airtel customer care as ivr gives lots of options!!

I wrote matter to facebook page but they are also not helping.
I'm attaching all of the screen shot, please help me out
