Ndn, I am glad that your players have not experienced any problems, but you are ignoring the large and endless amounts of valid problems by other gamblers.
Virtual & Co. may pay out the smaller wins, but as soon as you win more than average, you will end up in trouble sooner or later. I know several high rollers who have played with them over the last years, and all of them experienced the same: Slow payments & no payments en mass!
Personally, I am owed over $5k as a player by this company since four years. Whenever I decide to contact them about this again, they invent the most horrendous reasons not to pay, and make up new stories each time.
I do not touch the best converting affiliate program if I know that there are serious problems with their casinos.
