Help/advice regarding dialogue with bank to commence a chargeback

Really need urgent/valuable information on how to proceed with a chargeback for a large number of transactions to certain casinos.

I have been meaning to try and chargeback a couple of casinos going back to May of this year where I stupidly and illogicaly deposited a vast amount of my money only to then find out a large majority of these online casinos are criminals pretty much

Also I'm from Australia and these casinos are banned from operating or accepting players from Australia, yes I should have known etc but who gives a f#=$k I only want people who can understand where I'm coming from to relay advice and can appreciate a problem gambler trying to claw back hard earned dollars without remorse for the corrupt criminal fraudulent multi million dollar casinos

My issue is that I have absolutely zero idea how to approach the dialogue with my bank, am comfortable running the risk of not being truthful Also to my bank as I feel if I say 'online gambling' my chargeback chances wouldn't progress at all.

What do I say to my bank as the transactions I'd like to try and recover money from are not few here and there, they roughly add up to about 40-50 transactions with a majority of the transaction payment provider being some bullshit dodgy place in Nigeria.

Please could you offer advice as I have already left it very late and am approaching the max limit allowed to do a charge back. Thank u.

Hi, I saw that you already got to the tread where exactly such situations are solved and someone wrote you there. I think it would be best if you continue to post there and ask questions. 

I personally have never done a chargeback using a bank and I know that some players may have a problem with it. Also casinos, if you play somewhere and manage to make a chargeback, it is possible that you will not play in some of them again. Also, according to what I have heard from other players, banks don't always take this into account and in some cases, if you ask for a lot of transactions or something like that, they can close your bank account. So it is best to check with players who have experience with this and of course read the bank's instructions for such processes. I think that definitely something like that can be mentioned there.

I hope that everything will turn out well.
