jb maine bank customer care pe phone kya to bolte h "charge dispute jse koi cheej nhi hote or na he hum refund reference no ko track kr sakte h"

And this time Amazon send me this mail:-

I’m Vinay from the Amazon billing team with regards to the refund with the order #[protected] for Rs:13, 999.00

I'm providing a reference number as confirmation.

Here is the refund reference number:[protected]

Please contact customer service of your bank with this reference number they should be able to find the refund.

If you still don't see your refund then ask your bank's customer service to dispute the transaction as "refund never processed" under reference number[protected]

At that time, they'll see a pending refund and will follow the path back to our payment processor to locate the refund.
