This application is very good but customer support is very bad. Since 3month i am facing issue and they are not solving.My balance got deducted and i was not able to o enroll course.They said contact bank customer care. I got refund from bank.But i am not able to enroll any course.When i asked from Udemy customer care they said i want cancel to dispute from bank.Why you need this? As i mentioned i got refund then why you need this?. I wrote tons of mail still they didnt resolved
