Crypto Fans, What Do I Do?

So earlier today I used “Kraken” a platform to buy, sell and trade crypto currencies. I withdrew $300 from my kraken account but it accidentally went to my “Stake” gambling account when I meant to withdraw it to my bank. After a few hours I was able to get help from Stakes support team in returning my funds back to my Kraken account. That being said when i filled out the information to transfer it back to Kraken I accidentally forgot to put my destination tag. (Im new to this and don’t know what I’m doing) It shows Kraken received my money but my account didn’t. I contacted support and talked with someone for 10 minutes tops and then they left me. Nothing else was said. I’ve sent emails and messages but still nothing. So after stressing ALL day I have no idea what do to.

This is my first time using Kraken and any crypto platform in general. I’m very new with this stuff and I really don’t want to be out $300. I have no idea what I’m doing and Kraken has not been helpful ghosting me. So I turned to Reddit. What do I do? Am I out all of my money?
