Same here regarding Casumo. After a few half decent withdrawals a couple of months ago, I'm finding it difficult to even double my starting balance now, especially playing MGS games (from which the withdrawals mainly came from).
And the so-called rewards for levelling up (I'm at maximum level 180 and purple belt), are getting worse.
I was getting free spins on something decent and a cash amount, then it changed to free spins and a 20% bonus on my next deposit, and now, the last 'reward' I got was for just 10 x 50p spins on Gemmix
So I'm stopping depositing there
