Hi PragatiSuni103, don't worry about anything. I can tell you, that it is not your course, but udemy's 30 day refund policy that makes this happen. If a person buys this course, only with the intention of getting it free, then they will, buy the course, learn everything that you have to offer, and then ask for refund (and while doing that, they have to fill feedback, and that obviously would be a 1 star only so as to make their refund easier). Don't be discouraged, just keep doing what you are doing and all the best.
