Mass Effect 3 Online Pass, Unhelpful Support

I have followed all help tips I have seen online and reached out to support. I said at one point I had an EA play subscription and they asked for the dates when I had it. This was years ago so I don't know. I asked how to confirm and they said check your email and ended the chat with me. After 3 hours of trouble shooting I finally get someone to talk to and when I ask how to get the information for them they end the chat. This is an infuriating experience as all I want to do is play a game I purchased.

I bought ME3 through steam last night. Getting the authorization dlc error, got rid of all single player dlc to get rid of the error. Tried clearing temp files, moving liscense to the desktop and deleting it, and i have cleared cache on the EA app. Reinstalled the game twice. All the forums say to reach out to support but then for them to just "hang up" on me is ridiculous. Please can someone help me.
