Mass Effect 3 online pass error

No online pass on my game, can't play MP, the dlcs don't seem to be active. Been in chat with support for over 4 hours, speaking to like a dozen diffrent agents. 

They all seem clueless. 

Case #242969621

First I started with the steam digital deluxe edition, but clearly when you buy it, the EA server actually gives you the standard edition. 

Okay, so i've seen four or five threads with the same issue, just contact support and they'll fix it, right? 

Well actually getting in touch with support seems nigh impossible, the ai chatbot that masquerdes as support won't let you. But eventually I got though. The first support agent lied and said it was steam's fault and I needed to talk to them to 'prove that i'd bought the dlc' (it's a one item bundle, you HAVE to buy the dlc)

Anyway, i got in touch with another support agent who passed me off to another one, who got the Online Pass required to actually play MP. GREAT!
But not the dlc. 

The agent then says "reinstall the game and it'll all be fixed k thx bye" and closed the chat on me. 
I reinstall, and wouldn't you know it, not fixed. 

I get back in chat with a new agent, then my tab closes itself and I can't reopen it no matter what I do. 
While i'm 'afk' the new support agent 'fixes' my problem by doing something, which completely removes my permissions and ownership of the game entirely. 

So I've got from 'has the game but no dlc or online' to 'has the game with online but no dlc' to 'can't even boot the game because EA app is saying that I don't own it' 

After two more agents and like another hour of this, I eventually get one who just completely removes the steam version from my account at all, presumably writing it off as irrecoverably screwed up by the previous guy, and he gives me the EA version of the game. 
Great!

But no dlc or online. So i'm right back where I started.

I eventually get another new agent, who makes me reinstall the game again (for the fourth time total so far) claiming 'you definitely have all of the permissions, you just need to reinstall and it will work' 

I reinstall. No dice, doesn't work.

They say "We've logged this issue and will get back to you, when we find a solution, we'll send you a message in-game."
in-game? You're going to send me a message through Mass Effect 3?
Somehow I seriously doubt that.

Also, why would I even boot the game up unless I know the issue is fixed? It's not like i'm going to be playing it.

Also, the solution is simple. You just give me the online pass and the dlcs that come with the version of the game that I originally purchased. One of you literally already did that before another one of you screwed it up and took it back away from me again. 

Jesus, how is this so complicated? It's been five hours. Just give me what I paid for!
