Fight Night Champion DLCs are unavailable on the Xbox Marketplace

Fight Night Champion DLCs are unavailable on the Xbox 360 Marketplace. I own the digital base game but the DLCs Legendary Young George Foreman Exclusive and Heavyweight Legends Pack cannot be purchased or downloaded even though the base game is still available. I already contacted EA support and my case was registered and forwarded to the dedicated technical team but the case was closed without any response or resolution. Xbox support confirmed that they do not control DLC availability and that the responsibility lies with EA Games which manages licensing and distribution of additional content on the Marketplace. The Xbox 360 still maintains connection with the Marketplace allowing compatible games to be purchased and downloaded through the download history. No correction is currently available and there are public discussions on Reddit about this issue. I request that the problem be investigated that the DLCs be reactivated or that an alternative way to obtain them be provided and that my case be kept open until a solution is reached.
