[Resolved]  Aquaguard — no service man

We were bought a water purifier of aquagaurd one year ago. now there are particles coming in water and taste of water not good..we have already ask Bhubaneswar office(from where purchased) to send service man for repairing.But they sent us a service man of balangir who wants warenty card,we have no warenty card because our company purchased more than 7/8 water purifier at a time and we have only purchase order receipt.
so plz solve.
