[Resolved]  PayUMoney — payumoney not releasing the settlement amount

I used payumoney for my education videos website as a start-up we had promotion with instagram adds and after getting payment from 4-5 customers they blocked my account settlements and not replying to the mails also! The customers are also worried because they didn't get the service and they are not replying a single thing that they ll refund the amount or ll do settlement! They are just doing fraud things legally! I don't know why they do so? Please help to release the settlements
