Airtel — number starting showing all of sudden after a recharge

Address:

53593

My airtel number [protected] has stopped working all of a sudden. On the 3rd of may i did a recharge of 200 rs to replenish the balance. But soon after recharge was done the number was rendered out of service. Received no response from airtel customer service ([protected]@in. Airtel.com) despite emailing them twice.
I request the resumption of service to my phone number since i'm not able to receive otp from anywhere i've given this number.
