[Resolved]  Airtel — sim card service stopped for no reason

Address:

Airtel store, New Sangvi, 411027

My airtel sim card service is suddenly suspended for no reason, after that i called customer service, they said your sim is damaged, it's technical issue, you need to take new sim card from airtel gallery
I have taken new sim card for same number but after waiting for more than 12 hours it's not activated.
I called customer service more than 8 times still they do not have any resolution for this issue.
How many times i need to visit airtel store to activate my number??
My all communication is stopped due to this issue.
