Never go to koramangala Airtel Relationship center, you will have the worst customer experience. Funniest part is the cartoon of the store Mr. Dhanpal or Dhanapati (who is said to be the manager of the store) (not sure), who even dont know how to behave with a customer and became a manager. If they are frustated in handling the customer, please have this job resigned and look for something else. Lots of people with good experience are waiting in the market for customer relation.
Viewers please never go to koramangala Airtel Relationship Centre.
