My withdrawal was deposited into another bank account

On january 3 2019, I made a withdrawal for $800CAD to be deposited directly into my bank account. Which i found strange because about 6 weeks before i made my first withdrawal for $300 CAD. I used the instant online banking method to make about 65% of deposits using my debit card and the rest with my visa. So the same method was used for the initial withdrawal. It took about 2 weeks to finally receive my funds. Through the waiting period i kept playing and managed to get my winnings up to $900. I decided to withdrawal these funds and this is when i found out about the ID verification and was not able to access my fund's. This is where it starts to get strange. I was asked to provide document after document after document and still nothing. This went on for about a week and a half so i decided to make the withdrawal using the insta banking method. To my surprise i was told NO. This method is not available to you and need fo get account verified. I was also told to fill out my bank info so funds would be deposited directly into my bank account no third party involved like the first withdrawal i made. I said ok and went ahead to fill out the bank form provided. At the time I hadnt notice that the last digit in the institution number was incorrect. As i later found out this was a costly mkstake on my part which i acknowledge the moment i found out. Forward to Jan 2 i got verification finally and decided to withdrawal the funds. Confirmation came the following day jan 3 and was told the funds would be deposited in 1-5 business days. About two weeks pass still no funds and thats when i found out about the incorrect institution number so i notified leovegas right away and was told not too worry that this matter would be solved as the funds are probably floating around or frozen. I was asked to provide up to date bank statements on three separate occasions. Was also told that there is no need to keep contacting them that they would email me if anything. What i kept being told was that they were waiting for their provider to contact them. Never got one email this whole time not even a follow up by the way. On january 23 i finally got some news saying that the provider payed out the funds and had been deposited weeks ago on jan 4 2019 into the wrong account. So i was told pretty much that i will not be getting my funds.

I decided to phone leovegas and spoke to a very helpful lady about the outcome. She gave me some good advice and was very sympathetic about the situation. After talking to her i received a recepit from leovegas forwarded from their bank. It had all the info including the wrong instution number and the name of the bank in which my funds were deposited into. I bank with TD CANADA TRUST and my funds went to BMO. Not even the same bank! So i ran over to both my bank and BMO to explain the situation. At first they had no clue what i was saying and even made me feel a bit foolish. Not sure how i kept my cool but i did. So i came home home wrote an email to the manager of my bank explaining this whole ordeal and he responded right away with very specific details on how to fix all of this. I forwarded the email to the leovegas support team and still haven't heard back almost 48hrs later.

Does this mean that im out of luck and will not be getting my money because a mistake that can happen to anyone uncluding on their side? Why cant their provider ask the bank where the funds got deposited to retrieve and refund the money back? How can another bank accept a deposit if the name doesnt match the account number?

This doesn't make any sense to me and its very frustrating. Its taking alot out of me and financially im pretty much barely surviving. Work is very slow at the moment and i have even applied for a loan but got denied. My visa is maxed out and only have a few bucks in the bank. This $800 would be of great help right now.

If there is anyone out there that can help me please let me know. Any advice helps right now. I only want what is rightfully mine.

Thanks,

Carlos
