Airtel & Cellone is useless. They don't respect their customers. Airtel is really bad. I was an Airtel Pre-paid user.

When my parents call me from west bengal by cellone mobile phone they here that THE DIALED NO DOES NOT EXIST. My parents complaint BSNL-CELLONE customer care for a month but west bengal bsnl cellone customer care failed to solve it.

BOTH OF THEY BLAME TO OTHER SERVICE PROVIDER.
