Online casinos fined for failure of theirs systems safer gambling and deposit limits

[KL9933]

I had previously complained to the company about deposit limits as my limit was only 500 monthly but they said I won so I was able to deposits more. 
it was recently I read they had been fined for failures and time spent over 8. Hours non stop on max amount spin 3-5 pounds 

Do I have a positive position to get a refund for this?

any advice much appreciated 

Next case William hill I got a bonus buy 150 for 300 say but managed to win over 20000 I reached the target for bonus requirements but it just cancelled my balance and left with 2000 is this allowed, this is 3/4 years ago, 

 

thank u
