Yeah, I dont know how legal this is, as it is their address that the BCH is in,  so it is not lost. They have the private key to fix the problem. I am not sure how long this would actually take them..instead of writing me long emails about how they cant help me. I think is what happens when a company gets that big- they dont care about the individual customer anymore.

Hi,
thanks for your reply.
This is what Kraken replied to me:


"You are absolutely correct about us possessing the private keys in this circumstance. That being said, it isn't as straight forward as you might think. Kraken is a cryptocurrency exchange and the nature of cryptocurrency exchanges are wholly different from the experience you might have with a personal wallet where you have easy access to the private keys. With things like the theft of Mt Gox, the internal compromise of Shapeshift, the social engineering of BitPay, and others, we must put security as the paramount concern. As such, our exchange is setup in such a way that nobody within Kraken can unilaterally move funds. We believe that this is a very important protection that makes it extremely difficult for client funds to be stolen by external or internal parties.

Only a very small group of people at Kraken (devs) have the ability to access your funds given an auditable thorough process of checks and balances. This makes the process extremely resource (time) intensive for the devs that have very full plates and very little time to dedicate to any specific task. They must prioritize all of our tasks internally and the requests of clients as best they can. We think that the prioritization of improving our UI/UX as to avoid these type of mistakes will show the greatest dividends for our clients.

This is the second time they sent me a reply like this.
Do you have any advice on how to convince them to give me the private key or help me in any other way?

Hello,
Two days ago, I recovered my Bitcoin Cash from my BTC wallet. I read that Kraken is one of the sites that accepts Bitcoin cash so I made an account with them. Once I was registered and verified, I then went on to BTC and went through the recovery site to get my BCH. After recovery, it prompted me for an address to send it to. I then went on to my Kraken account and looked for a BCH funding address for the deposit but there was none. I panicked, as the recovery site wanted and address then and there to send it to and i could not find the right one. I then produced a BTC address instead and used it to send the Bitcoin Cash there. This was obviously not a good idea- I have been waiting for the money for over two days now and it seems to have disappeared.
I have since talked to both BTC.com and Kraken support. BTC.com have told me that they have sent the BCH and that it is a confirmed transaction on the bloc, which makes sense to me. Kraken, on the other hand, have referred to an email that they sent out before I signed up with them, telling people not to send the BCH to a BTC address and that it is very resource intensive to recover lost crypto currencies, so they will not bother helping me and instead use the time to create an open post for this mistake to be prevented in the future.
If it is a confirmed transaction, does that mean that Kraken has the BCH somewhere in their system or my address and is it legal for them to hold on to it? This is a matter of 14.2 BCH and I cannot see how this can just be ignored by Kraken because of "resource intensive" work? Too bad, so sad?
Is there any possibility for me to get it back??
I would appreciate any advice on this.
Thank you!!
