Meesho refund stuck for weeks after they said they refunded both my amounts , SBI says there's no refund to trace. What do I do?

Need some advice because I'm honestly stuck.

I ordered something from Meesho and later cancelled it. One refund has been pending since 8 June and another since 18 June. I paid through Paytm UPI linked to my SBI account.

I've contacted Meesho multiple times. First they told me the refund was initiated, then later they said it wasn't initiated. After that they kept saying it's under review and finally told me to raise a chargeback with my bank.

I contacted SBI, but they said they can't see any incoming refund or failed refund transaction on their end, so they can't do anything and asked me to contact Meesho again. Meesho also never gave me any refund UTR/RRN.

I already filed a complaint with the National Consumer Helpline for the first order, but Meesho's response there was basically "raise a chargeback", which SBI is saying they can't help with because they don't see any refund at all.

Now I'm just going in circles between Meesho and SBI.

Has anyone dealt with something similar? What should I do next? Should I wait, file another complaint, or go straight to the Consumer Commission?

Any advice would really help. Thanks.

The amount is not that big but I am a student and i don't get much money so this amount is big for me so please i would really appreciate any help on what should I do next
