No reason was given to me and told me to contact marketing manager. I tried to emailed to your mentioned address too but no response till now.
Since how long have you been facing the problem? And when did you send an email to their marketing team? Have you withdrawn your affiliate commission before? There could be several reasons for such issues. It will take some time if there are any errors in calculating your commissions. Otherwise, this problem can happen for self-affiliation or referring people of restricted countries. Can you add some screenshots here which reflect your issue?
