Indian Oil Corporation [IOC] — not accepting payment through debit and credit cards

Address:

In nandyal Beside bommalasatram flyover, Kurnool, Andhra Pradesh, 518501

I have been visitng the petrolpump from past 6days.. They have the facitiy to swipe card but the staff is saying that it will take time for them to settle and sort out the transcations at the end of the day.. Today i noticed an online transaction has happened by seeing the payment slip but the staff refused my payment through staff... Is this the way the staff work and respond to the customers.. And while india is racing towards the digital and online payments i dont know how indian oil corporation is lagging.. Ioc will be loosing its valuable customers if they keep on maintaining the staff like this
