Brand registry approved but no brands under my brands

Hi, I am a reseller. Accepted a brands invitation to their brand registry. However, when I go to my brands no brands show under and the brands doesnt show me as a role user either. My conclusion has been when I get accepted, Amazon shows in my acceptance email a different merchant token than mine. I have tried responding to the only way possible via the case of acceptance and they do not respond to me. I am stuck in a loop of them telling me I am accepted but no real help after. Anyone have any suggestions?
