www.airtel.com opens Vodafone site :-)

This morning when I was trying to view my Airtel bill, I managed to open www.airtel.com but to my surprise, I saw that it was redirected to vodafone site. For a second I thought has Airtel been brought over by Vodafone ?

but the truth was it was a DNS ( Domain Naming System) entry that points

www.airtel.com --- > http://www.vodafone.es/particulares/.
I did some googling to find if I was the only one but I saw few guys did notice this. The actual website of Airtel being www.airtel.in.

I brought this to the notice of Airtel Customer Care, I only hope they will take some action.
