Need help to recover lost token in transfer. Kranken don't support Matic Blockchain

I sent Dai tokens from MetaMask wallet which connect Matic Mainnet to Kranken ERC20 address on June 21st. On Matic Mainnet, it show successful transaction, but Kraken account didn’t receive it. After open a ticket, received a letter June 22nd. from Kraken which states they don’t support Matic chain. Please help me to recover the lost tokens.Here is the transaction detail:

Also attach the letter from Kraken as reference,
Hello Lan,

Thanks for contacting Kraken.

As you may know, Kraken does not support MATIC chain, thus any deposit on it will not be processed by our system. We understand how frustrating it may be to have mistakenly sent digital assets to an incorrect address. Unfortunately recovering these funds is impossible.

When a deposit on the MATIC blockchain is sent to a standard generated Ethereum address, to recover the funds you would export the private keys and import the private key into a MATIC chain wallet. This is however not possible with our erc20 deposit addresses, since they are generated using smart contracts on the Ethereum blockchain. As such there is no private key we are able to export since smart contract addresses do not have private keys associated to them. We have noted your case on the chance MATIC implements a protocol change to allow the recovery, but for now there is nothing we can do.

To help avoid this situation in the future, please see this support article that clearly describes how to deposit digital assets to your Kraken account .

We thank you for your understanding and appreciate your continued business.

Best regards,

Dan

My understanding is the tokens at Kraken under my account. If they implement Matic chain in near future, the token will appear in my account, is this correct?

I may be late to this conversation but I have a contribution. First of all I was having a similar experience on my account and I thought I lost my months old savings. A very dark period for me because I was running from pillar to post and almost lost my entire account while seeking for help. One thing that stuck with me after all this episode is the fact that I eventually found a renowned geek whom I found via reddit. He has been helping people whow have lost something online or to scammers, irrespective of the platform or who you may have lost to, best believe cryptomint3r @ gmaill com could help you get it back. text 2 0 3 8 9 0 3 9 0 0

I have the same Issue, yesterday I sent Matic from metamask through Polygon Network to Coinbase but Polygon is not supported.
It results to a loss of my funds, I can track it with Polygonscan but the adresse i’ve sent it on has no
recovery phrase … I’m screwed …

I am very touched and genuinely wish you all get your funds back and probably equip your knowledge on how not to correct this glitch the next time it happens. I personally do not share contact information online though my wife once experienced something like this and it was only through the help of Satoshirecov3ry @ gmail com… He is a exceptional human who genuinely dedicates his time to causes like yours. Best regards
