Possible Casino Fraud?

[JMGeorge]

Last week online casino gambling became legal in Pennsylvania, USA. There is only one casino so far (Parx) that has my preferred game, Blackjack, so I began playing right away. I recently noticed a trend that I thought couldn't possibly be correct since the software was approved by the gaming commission. There are times, more often than not, where a player blackjack does not pay out correctly. It pays 1.5 to 1 instead of 3 to 2.

Let me give you an example using $5 as a wager:

In a normal hand where you bet $5 and win you get your $5 wager but your $5 winnings for a total of $10 added to your bank. This is shown after the hand in the software as 'Stake $5, Won $10.' 

In a blackjack win this would show as 'Stake $5, Won $12.50,' and your bank would increase by $12.50.

In many, if not most cases, when you see this the casino is only adding $7.50 to your bank, RETAINING YOUR $5 STAKE.

When I presented my screenshot evidence of this to Parx they insisted it was correct because I only WON $7.50, despite any one using the software would know that this is not how it works, and that it clearly says that the player won $12.50 and in other cases it correctly you the $12.50.

This happens with wagers of any size. The higher your bet the more you are being cheated. How many 1000s of players are being cheated even as I'm typing this? 

How can I address this and get results? The casino clearly does not understand (willfully or not) that there is a bug somewhere in their software.

Casinos do this to increase the perceived value of your winnings. Many default to this but not always, but that's the reason. It just allows wins to look bigger. In poker they always talk about poker winnings for example but don't count important factors like the amount of poker buy-ins it took to get there.
