"the reference number of the refund is ref - 74332749082908129840501
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 response 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.
