So I spoke with my bank and explained the issue. They said they would not be issuing a chargeback as per visa regulations regarding gambling transactions.
They said this was because it was Visa policy in such matters and that I had invalidated the chargeback since I had given the operator my card details. They said I should go to trading standards or a govenmental body to complain.
I explained that because the casino had acted fraudulently in being unregulated in the UK in the first place there was no Trading standard body or govenment department I could go to as they dont carry a UK licence. The bank rep just sounded out of their depth and gave a 'computer says no' response.
I am a bit vexed. If I had lied and told the bank 'oh I dont recognise these transactions somone has used my card without permission' they would have most probably given the chargeback.
Not sure if I shoudl push the bank further on the matter
push further, if not say you will complain to the financial ombudsman, or better yet show them cases from the financial ombudsman regarding chargebacks
report it to the police first ( actionfraud), use the reference and give it to your bank
