Dear rajeshbalkrishnan
There are sellers who offer item on COD basis in select cities and ebay protects all transactions under our Buyer Protection Program and if the payment is made through PaisaPay the protection is upto Rs 50,000/-
The feature Ask Seller Question is helpful and you can seek clarification from the seller from whom you are planning to buy and the seller feedback from other buyers is another indication on how good the seller is
For our users we assist through Live Chat and email support and for correspondence you can send letter to our PO Box Address
