In theory, chargebacks are there to prevent customers from 'errors' by vendors.
Over the years, it has happened to me on a number of occassions. Double charging and in one case (with an accredited casino), I was charged over £2,000 having not logged on for several weeks. As you can imagine, I was not too chuffed but it got resolved with a little compensation as well.
I think that somes players, if they were honest, may see chargebacks as a 'loophole' to claiming back losses. Although I agree with a previous post in that this is technically fraud, I believe there is an area that could be 'legitimately' pursued.
When you deposit at a casino, often the name appearing on your credit card is NOT the name of the casino. We all know why they do this and it's being discussed before - it's a way of 'disguising' the transaction often so as not to appear as a gambling one. There are many reasons for this - legislation within the country in question, to stop transactions being declined etc.
Sometimes these 'ficticious names' are not the same as advised when you make the transaction e.g. the message comes up "your transaction will appear as playpoker.com or playblackjack.com or etc. but it actually comes in as fruitshop.com. If you are not advised of the correct name at the outset, you could legitimately complain to the credit card company that you don't know who the transaction is for. In this instance, the credit card company would go back to the casino. It is unlikely that the casino would pursue the matter (outside of asking you to accept it) as they arguably shouldn't be trying to 'trick' the credit card companies to begin with. Even if you are told you will be charged as fruitshop.com, you could still lodge a complaint with the credit card company as the casino should not be using a 'front' to 'trick' credit card companies.
Of course, it is not against any law for casinos (or any company for that matter) to use trading names for their companies. However, when this is done purely to maximise the transactions that are passed, I believe that by default, they are encouraging players to mislead their own credit card companies by helping them make the transaction to begin with.
Clearly if you pursue chargebacks, it will be looked at very dimly by the casinos and be prepared to have your account suspended and blacklisted. However, last month.....with one accredited casino.....I have received 5 different names on my credit card statements for transactions I have made. Sorry, this doesn't really seem right and if pursued, I suspect that the credit card companies would refund back the money and it is unlikely the casino in question would pursue further.
Morals is a tricky one when it comes to casinos because it normally relates to whether you have won or lost....!
