Address:

63,sindh vihar colony, nadi gate, laskhar, Gwalior, Madhya Pradesh, 474001

I had called my upc code on 18-dec-2019and i had submitted all my documents in bsnl office on that day itself with upc code expiring on 22-dec-2019. They told me to wait for 4-5 days for activation. And till today on 26-dec-2019 they haven't activated it and today i got the message that "sorry ur port request is rejected as the validity o[censored]pc code is expired. I don't know why bsnl do this type of slow work. What can i do now and for again taking the new upc code, i have to recharge my phone no. Because it's validity got expired. I have to complain against the bsnl for doing this type of slow work.
