Refusing payout, unfairly accusing me of breaching a term

I got a letter on monday;

Dear Mr. < removed >

After examining your gaming records it is clear that you did not violate any betting limits. After making your 100 euro deposit on 19 February your largest bets were for 10 euro each. After 20 Feb 21:47 when you made your smaller deposits, you bet only 2 euro each spin. The financial department and the support staff were confused, and we very much regret that.

However, in your case an additional factor comes in to consideration. The General T&Cs (13.5) stipulate that: “If a player's accumulated deposit amount does not exceed €200, player will be entitled only up to X10 last deposit. This maximum payout will be enforced also in cases where the player made additional deposits which were deemed at the sole discretion of the Casino to have been made in order to exceed the €200 accumulated deposit amount.” We call this the “new Player Rule” Most all casinos this rule is applied to those who have received a bonus. In our case we have this rule for all depositors.

The reason why we have this rule is to discourage “hit and run” players of all sorts, not just those motivated by a desire to play with big bonuses. In addition our policy is to be generous with bonuses for any depositing player who wants them. Obligating all new players to abide by this rule, balances out the fact that we allow our established clients to play with generous bonuses after you cross the 200 euro line and keep all your winnings.

This means that you are entitled to receive only 1000 euro from your 100 euro deposit. This sum we will be happy to pay you. In addition we would like to add an additional 300 euro for your time and trouble in setting this straight. Perhaps you may find comfort in the fact that 130% return on 100 euro is a very fine investment by any standard.

Sincerely,

Karl Z Michaels

This means that there is a "hidden" term/cond that states that if you deposit less than 200 Euro, you want be abile to withdraw more than 10xdeposit. In my case they are willing to pay additional 300 euro, a grand total of 1300 euro (I had 4900 euro so loosing 3600 euro on the witdraw). I have contacted Karl asking about getting my money back on the account for either playing on or withdraw etc, but since monday I have heard nothing. Also in live chat they dont know anything.

I think that they where "nice" giving me 300 euro ekstra, but still loosing 3600 euro to T&C that is just stupid. Lets see if my money appear sometime soon. This is why I always read T&C, but missed out on this one, since its the first time I ever heard about such a stupid T&C.
