Does the withdrawal page show the withdrawal request?  If the funds are still counted in your account, then the funds haven't been deducted for the withdrawal request.  I would try to create the withdrawal request again.  Maybe the first request failed to be recorded by Kraken's servers (bad HTTP request?  Cloud flare issue?).

I started a withdrawal request last month (still waiting for the funds to arrive), and I am sure the funds were deducted right away, before they even accepted the request.

I have been waiting a month for a CAD withdrawal to go through.  The withdrawal has been stuck in the "sending" status for a month.

Created a support request 2 weeks ago, but they didn't really help at all, just kept sending the same reply and closing my request.

Then they requested that I attach a screenshot of my bank account, but the support website doesn't support attachments and replying to the support emails doesn't do anything.  Asking for a screenshot of my bank account, seems to me to just be a way do delay doing any real work on the request.

A screenshot of my bank account is not going to show any useful information.  I had already included full details of my bank information and the withdrawal when I opened the request.

Please take a look at request #425160 (a follow-up of my original request).  #387314 was the original request I opened, but was closed and marked as resolved even though the issue hasn't been resolved.

I am about ready to try to fill a complaint against "Kraken Client Engagement" person "Will", since he just cared about marking my request a resolved, instead of doing any real work.  Customer really shouldn't have to be coming to a public forum to get someone to take their support request seriously.

Thanks,

Even if you can't recover the Private-key for the receiving address, keep both your wallet backups safe and don't give-up and delete them.  The BTCs might still be unclaimed by the address that you lost, maybe in the future the network rules will be changed to allow old (1 year, 6 months) unclaimed transactions to be reversed.  I really think this should be possible.  It will require a change to most of the bitcoin clients on the network before any block containing a "return unclaimed BTCs" transaction will be accepted.

Lookup the sending/receiving address on http://blockexplorer.com/ and find the transaction/block that contains the lost BTCs.

Also I think that new wallets should default to returning change back to the sending address, let people that want anonymous transactions to change to the current method of sending change to a new address.
