Fair enough mate, but you don't gamble to get freebies back. You know full well when you deposit that most times your money is toast. Nature of the beast.
Whilst I understand it is nice to get something back, I think VS gets it right for the lower depositors - I'm certainly happy with their retention strategy for my player profile (although the amount of freespins need to be increased in the normal battles).
This being said, I do have some sympathy for the larger depositors (like yourself), as their doesn't seem to be much of a VIP programme anymore I believe?
Not having a pop at you as a person but you do seem to want a hell of a lot from VS. You also say you're losing and can't win a lot. Join the club mate. A majority of people are in that boat

It's certainly not unique to yourself.
