Flipkart — I have got the refund

I had placed an order with Flipkart on 17 August 2025 . Later I cancelled that order. I had paid for that order thru Google Pay(Infinix Micro USB Cable 2 A 1 m, 18 Watt…..)But Flipkart is claiming it has issued a refund amount being Rs.150. But till today I have not got the refund. I checked with the bank(sbi). They are saying they have not got the money. Flipkart not ready to pay saying all sorts of excuses. I waited till today. But no refund yet. Will you help me to get the refund?
