False promotions

I have been a longtime player at Winpalace. I always play blackjack or perfect pairs blackjack. I enjoy talking to the agents on live chat, most are very helpful and friendly. Tonight I deposited money to play and instead of going thru live chat to collect on a bonus, I noticed at the bottom of the screen, a running advertisement for a promotion, it said if yu deposit 21 dollars or more get 194 percent bonus...use takeall1 for the code, then it said deposit 100. dollars or more get...whatever percent it was use code takeall2. and so on. I deposited 50.00 dollars, redeemed the bonus and played. I worked my way up to a little over 1000.00 dollars and went in to the cashier box to see where I was at with the play thru. There was no playthrough amout listed so I called the casino and spoke with Jake the manager. I wanted to know how much I could withdrawal. Evidently, the Takeall1 code is just for slots. So, all the time and money spent was worth nothing. When i told Jake that it was not specified the code was just for slots on the bottom of the screen, he said well, it wasn't specified for tables either. He said it was my fault for not reading the coupon details on the redeem code page. Don't they have to honor the winnings because of the way they advertised their promotion? or is it my fault. By the way, Jake the manager with whom I spoke with was the one put the promo on the website. When I asked for the email of his boss, he said just to email him and he will make sure it gets to the right person. Is this normal protocol, or is he trying to save his job?
