Dear Sir/madam,

Somebody got issued mobile no. [protected] in my name and abusing to other persons. A person came to my home and says " he is getting call from this no. and it belongs to you and your address" i surprised that i never applied for this no. and how it happened. Then i blocked this sim card from airtel. but i want to know how any person can issue the sim from my name and address.
