Airtel — Duplicate SIM not yet activated

Address:

Chennai

I applied for and got a duplicate SIM for my prepaid connection, owing to signal issues in my existing SIM. I visited the Airtel store at Ashok Nagar, Chennai and got the work done.
Date[protected] pm.
The old SIM got deactivated on Saturday night, while the new SIM is not yet activated (even after 36 hours).
Please resolve at the earliest.
