It offers good discount on bigbasket.com and other sites, but since last two txn.s its hanging and problem is that they never revert the failed txns back and credit back to the bank. Their SMS says that txn. is successful but seller site does not get money and good are delivered.
This has happened with my twice and came to know about it when goods were not delivered to me and traced back and saw that money was never credited to the seller account.
Moreover, their contact phone number is not picked up and I called them through STD and waited in call queue for 10 minutes and it was not picked up even.
Do not trust such payment options which cannot automatically detect failed txns. and revert them back to the buyers. Payumoney seems to be one of them !
