Fiserv is worst company. Pinelabs and hdfc are much better. They give you address, email and phone number of senior managers if any problems arise.

nodal.escalation@fiserv.com just creats a ticket automatically and ticket is closed next day automatically saying issue resolved.
I have finally asked cardholders to file chargeback against me.
Most chargebacks are still in verification phase once i receive them will get to know further updates.
Chargeback for 2 transaction is processed and i accepted it. They said they're reversing transaction but it's been 10 days still customer hasn't got any refund..
There is penalty for chargebacks. Their schedule of charges say it's 600rs per transaction. But nothing is confirmed as nothing is fixed , they do not reveal correct charges for anything. Charges are different for every merchant
