I'm highly dissatisfied with Airtel Koramangala (Bangalore) outlet. There is no need for such an outlet at all.
* They make you wait like hell to pay your bills to address your issues.
* When you make a payment they don't provide you the bill. At the end you will be surprised to get a call from airtel customer service and tell you that your payment has not been posted. No matter how long you wait or argue you will either have to repay the bill to continue the service or throw away the stupid connection, as I did.
BEWARE OF AIRTEL KORAMANGALA ( OPP TO SHANTI SAGAR ) THEY 'LL CHEAT YOU AND MAKE YOUR LIFE MISERABLE. ALWAYS ASK FOR BILL OR MAKE PAYMENT IN SOME OTHER OUTLET.
