Vodafone beats Airtel

How would you differentiate the best service provider from other normal/ordinary service provider? The answer is very simple, by the service they provide. I lost both my airtel and vodafone sim card and i went to the respective kiosks to request for a new sim card. First, I went to the Vodafone kiosk and i was assisted by a representative in getting my token number. When my turn came, i went to the help desk and explained my requirement. They requested me to fill a form and for my identity proof (usually they ask for a photocopy, as the kiosk had the photocopier machine, i didn't have to carry one) to take a photocopy of it. Then they asked me to get an invoice for 15 rs. (sim replacement charges) 2 steps from the helpdesk they had the cash counter. I went to pay the charges, the executive at the counter asked me for the details and she said i don't have to pay it right away and it will be added to my subsequent bill (this is what i call customer service). They provided me with a new sim and i had difficulty in inserting it in the phone, Vodafone personnels helped me in removing the older sim which was stuck in the phone and inserted the new sim to the phone (this is a value add). Now lets compare the service of Vodafone to Airtel (i hold bharti stocks in the market) I went to their kiosk and they had someone at the token counter and they asked me for the purpose of my visit and my airtel number. They keyed in the necessary information and the IVR threw out a number (it was eco-friendly) I remembered my number and waited for my turn. When my turn came, i went to the appropriate helpdesk and told them my requirement. She asked me to fill a form and for a photocopy of my identity proof. When i said, i didn't carry my ID proof, she suggested that i could go to a shop in the same complex to get a copy of it (I was surprised, immediately reflected on the service at Vodafone) I came back with a copy. Then the executive asked me to pay 25 rs. at the counter, i didn't carry enough money in hand, so i gave her my credit card. She said they won't be able to process the card and insisted on cash. I told them they can include the charges in my subsequent bill (again Vodafone came to my mind) She said it won't be possible and i need to pay the money then and there to process my request, i was left with no choice but to pay them in cash. I was able to understand that Vodafone had their own center and Bharti had outsourced their services. Whatever be the case, Vodafone's service was so refreshing and Airtel's was so forgettable.
