I have set the caller tune. But it was not activeted. So i asked at customer care two times. Then also they didn't work for this. After that i deactivated it, and again after 1 days again try to activate it then also i got the confirmation message that callertune has been set but when i checked it it was not activated. Again I call at customer care they said it will take 24 hrs. Is this kind of service they provide? Really i was very upset with the callertune service of Vodafone. read full review »
