On the 10th of June, after making two successful deposits of 20 euros at mrBit casino, I made a third deposit of 15 euros.
I made the deposit via Multibanco, so I get a separate window with the reference for the deposit. The money was gone from my bank account but the deposit was rejected at the casino. I reached out to support, where they asked me for proof of payment, which I've sent - a screenshot from my bank account with the details of the payment, including the multibanco reference and the money withdrawn from my bank account. They informed me that they needed a receipt from the bank, which is not possible, since the payment was made via Multibanco, so the bank has nothing to do with it. They also asked me for a screenshot of the reference, which again is not possible, since after the deposit is made, the screen just goes blank, even though in the URL bar you can see the deposit was successful on my part.
I really think I've provided enough proof from my side regarding the deposit, and it's up to the casino to confirm what happened with the Multibanco reference (that they have) and where did the money went - I've even waited two days to see if the money somehow appeared again on my bank account, which it didn't.
Attached follows the same screenshots I've sent to mr Bit support.
Thank you for your help.
