How can i check my Battlefield's DLC is it really owning or not.

I did contact EA help because i can't found those 5 weapons in Battlefield 1.

And the EA help said i purchase the Deluxe edition (not pre order).

So i can't access the 5 weapon in Battlefield 1.

The Origin said the DLC is unlocked which make me confused that do i actually own the DLC or not?

@Jacky10X-OIm not a PC player so don't use Origin but my understanding is that you own the DLC and just need to install it. You may need to go back to EA Help and continue discussing this with them really though, other than advice we can't help a great deal with account issues on AHQ.

Thinking out load it may just be that it's no longer available to download (it was a BFV Deluxe Edition pre-order bonus after all). Certainly the only places I can find it now are dodgy looking or unofficial CD Key reseller sites. Something tells me I'm incorrect there though.

Thank for replying. 

this make me confused

because I don't know is it really owning the DLC or not and i can't check how i got this DLC

(because it is a long time ago and origin's order history only show the products that were bought via Origin Store. Code is not including it

So i assuming it maybe code activation or otherwise it maybe glitch

But I found out that i have the Firestorm Ranger set in my Battlefield V. And the Firestorm Ranger is included in Enlister offer (which is pre-order bonus(?), if the information is wrong please correct me) 

But i don't see 5 weapons in the Battlefield 1.

The reason i don't want to contact EA help again because i have a bad experience while contacting the EA help.

Which is not helping and just told me i purchase the Deluxe Edition and that is why i cannot access these 5 weapons in Battlefield 1 

I said i send a photo to them and they said they can check my account

When i said check my owning DLC and i immediately got reply said i purchase Deluxe Edition (no pre-order) so no access to them.

(I doubt is the game advisor really check my DLC or not because the origin client said i own it but the game advisor mainly focus on i purchase Deluxe Edition so i can't access them)

I want to confirm something?

Question 1: Is Battlefield V release on November 20, 2018 right?

If Question 1 is right, then

if i bought this game before November 20, 2018, do i still count as pre order right?

Edit: Just found out there are people also get the enlister offer content after the release date by redeem the code. And it contain all content including the 5 enlister offer weapons in Battlefield 1
