This Ideally is not not an issue at Jupiter’s end. Multiple large stores usually follow this practice where their POS terminals are linked to different entities which are linked to different MCC.
It happened with me when i paid for subscription and after few days i visited Reliance trends but still i got cashback according 1%. Jupiter bot system is worst and it didn’t help me at all. But it totally work good with Amazon Flipkart and Myntra.
Same thing happened with me as well at the zudio in Star Bazaar near kundalhalli signal. I paid at zudio but the merchant name was started bazaar and got 1% cashback
