Hi there,
just to be sure, is the missing IBAN truly the case here? Bank statements usually serve as proof of address, bank account ownership, or proof of deposit.
For such purposes, it is indeed imparative that such a document contains your full name, address, and banking details.
Can you provide another document showing your IBAN and other details that can be matched with the aforementioned banking statement? I have to admit I have never heard of "Banco Santander Totta" before, but I'd like to help you out anyway. How about you paste a screenshot showing the casino's request or response given when you submitted the bank statement? Even a simple copied and pasted text helps out. Perhaps I missed something important or just didn't understand the problem correctly.
