At this moment, there is only one way. You copy the transaction hash from the exchanger and take a screenshot. Since the fund has been successfully sent from the exchanger's site. Then enter bitz casino, contact CS and provide this information. This will resolve your issue.
Because this information is very strong and the only way to solve the problem. So do not be discouraged, establish contact with them and since the minimum limit for deposit is very low. I hope, your sol deposit address is correct.
At this point what actually matter is getting a clear response from the support team. If the transaction was successful from the exchanger side and the TXID has been sent, they should at least be able to find out what is causing this delay.
I totally understand how frustrating the whole situation is to the user for waiting about 3 days without seeing your deposit. I think he should just be patient, and hopefully I believe that the support team will respond and provide an explanation of the issue soon.
I have never had any issues with deposit though, because everytime I make deposit the transaction use to be fast and smooth.
After a day, I think, I followed up with support on the website, and they told me that the transaction was verified and it was already credited to my account. I checked it, and it was actually there. Weird enough it wasn't showing the first time I opened the account on the top middle, the balance was still low, so I thought it wasn't credited, but after asking, it was there when I checked it in the accounts.
Ohhh it's a good thing that your deposit has been credited.
