Hsbc live+ cashback issue
I have a hsbc live+ card. I made transactions of around 19000 rupees. 11500 comes under 10% and 7500 rupees in flipkart for buying a cooler. But So this 7500 should be a 1.5% category. But I got only 1000 rupees. After calling hsbc customer care they told me all my transactions are eligible for 10% cashback. I asked them what is the MCC for this 7500 transaction they told me 5411. Is there any way to tell them that it is not? Or do I have to accept that MCC is not under the bank's control?
