Incomplete Account Merge. Missing 7 Mac DLCs.

I merged accounts on Saturday, but 2 expansion packs and 5 kits (all mac/pc) did not transfer. I know there are risks to every merger, but I feel these should be transferable and that the agents I have talked to in live chat have not tried. I have proof of purchase and order numbers for all of the titles.

I am missing Adventure Awaits, Businesses & Hobbies, and 5 kits: slumber party, sweet allure, essential glam, casanova cove, business chic. 

I contacted EA help, but the agent informed me that "only PC-based games" are transferable. He then left immediately after telling me this.

I started a new chat and I explained that all 7 of these packs were purchased on Macbook through the EA app, which uses the same licensing as PC, so they should be transferable (in my understanding). The second agent then said they could not help because the other account is now deactivated and they could not verify the purchases, even though I sent screenshots of all the receipts that included specific order numbers. They seemed to refuse to look at my proof of purchase, and the chat was ended.

Since these are all mac/pc entitlements and I have the order numbers and email receipts for all 7 items, I believe I need a manual entitlement grant.

Can a community manager please look into this or escalate this to someone who has the permission to access deactivated account histories and verify my order IDs?

Or has anyone else experienced this and have advice? Am I out of luck here?
