Grid 2019 unable to access season DLC

Hi 

I spoke to someone on support already and he has asked me to post here as they where unable to help as this may need a store fix.

Back in 2020 I purchased the Ultimate edition of GRID 2019 from the playstation store.

As I understand it the ultimate edition should have included the following DLC

GRID season 1
GRID season 2
GRID season 3
Aston Martin
VIP Pass

But when I have checked my account I only have the following two DLC

Aston Martin
VIP Pass

I assume this is because I needed to click the download links in game to get the season passes added to my PSN account.

As many games don't automatically add the DLC to your account they just make it "free" in the PSN store and you then to download it manually before it is added to your account Dirt 2.0 is another game which works this way.

The issues is as the DLC for GRID 2019 has now been delisted I cannot download it to my account. As the store page is now broken see the picture attached.

The only fixes I can see for this are if the downloads for the 3 season passes are added back to the playstation store for users that had purchased the game prior to it's removal or if they can be manually added to my account by sony maybe? As I would like access to the content I paid for. I still have a copy of my receipt from the PSN store if that is required. 

Thanks
