I have read this problem before, but thank you for reminding users. In my opinion, this situation 100% user's fault, and if this ever happens to me, then I will not blame anyone. Each person must double or triple check transaction details before pressing the send button, and this behavior must also be applied everywhere. You are lucky this time they want to refund your bitcoin. I also rate 100% towards atomic wallet developer for being careless in releasing products. I can concede one person's mistakes, but what is the point of a team if they don't work together. You should use the bitcoin core wallet developed by bitcoin developers. There is a mobile version for Android users.
