hi, this is nothing new. there is no need to worry if you have paid with paisapay. as long as you don't mark the item received, your money is safe. once the time period for receiving the item lapses, you can mark the item as not received in paisapay. then seller will have to produce a valid proof-of-delivery if he has to receive his money which will not be present since you haven't received the item.
make sure you leave appropriate feedback for the seller once everything is complete.
