Why don't you send an email about the refund policy to every registered user instead of asking them to send a refund request? And why have you
added those users in your distrust list who have left negative feedback on your account.
Given not everybody check their email every day and some even put their email notification on silence, I think
ryzaadit's
suggestion will have better coverage. Broadcasting it on their media, all of the media they have, will helps convey this refund plan better --supposing they're true with their intention.
Otherwise, I agree that only informing the refund here and TG and then giving it a 30 days deadline seems very unfair.
