"the reference number of the refund is ref -# 1cvhqwzm0000k19y5yi5.
But, the refund has not been received yet.
Bank is saying no amount has been received by them. I've talked to them again and again but no responss is coming. So i need to file a"charge dispute" on them, to get the full details.
I need bank to resolve this issue as soon as possible or i'm gonna take some legal action.
