[Resolved]  Grofers — amount debited twice

I ordered groceries online through grofers but the amount is debited twice from my card, for the same transaction. I am showing the screen shot of my bank to them through their chat screen in app but they are continuously dis agreeing the dual receipt of amount. Whereas bank confirms me that it is claimed twice by the grofers. Therefore still grofers is not giving me credit of extra amount charged by them.
