Dear All,
I am holding a SBI FBB Credit card, Card Number for the same is [protected] .On 8th of July I have purchased one samsung mobile Amounting Rs 15964 / through Amazon app. I have purchased the same through EMI. Same day I erroneously purchased the same mobile for the second time which I later on cancelled through amazon. But my EMI instruction not cancelled by SBI .
But in my credit statement there is same 15964/ amount showing as twice debited & EMI also showing twice amounting Rs 2770/. I have alredy made double EMI payment for three continuous month (Aug/sep/oct, 20)
Request you please revert on the same asap & arrange to refund me double EMI amount for three month I.E 8310
