This is the worst app. I wrote more than 5 mails I don't get revert. I don't have any dues I cleared all my dues on 11th Feb but these people are saying they didn't receive the money.. I got confirmation from my bank as well. I have attached statement copy also.. Still I didn't get any revert. Don't use this app. .
