Aircel — aircel not working

Address:

Kolkata, West Bengal, 700006

After much trouble i got the port code for my aircel number [protected], as dk246913 and tried to port it to bsnl, but aircel is not sending the required port information to bsnl to complete the process. The status says canceled after two attempts, the latest on 21.03.2018
Now, even the customer service voice call has stopped working for aircel to generate a new port code for re-doing the process.
My old number was submitted in almost all official documents.
