Yes same thing happened to me pretty much. I am an experienced online sports bettor and someone told me about this site "free 100" for signing up. So, since I am familiar with "free$" offers on sportsbooks I called to get the rules regarding the Free100. I was told 20x rollover and max is $2000. They said nothing else, so I rolled it more then 20x's and over $2000 and requested a withdrawal and was told I would only receive $200 of the $2000. I was upset because I wasted a bunch of wins that I will not be compensated for, but I figured whatever I'll take the $200 and never go the site again. Then I submitted my withdrawal request again for the $200. I then receive an email saying, No ML or live wagering bets I made don't count as rollover. Again, I don't mind those rules, but was never told about them til after I requested a withdrawal. So my withdrawal has been canceled and they will not pay me out since I "did not follow the guidelines" of which I was never told.
Horrible site. I would recommend 5dimes or Heritagesports.eu. Great sites, no problems paying out and rules stated on sites and voice recordings of phone calls if anything is argued of what was told and wasn't.
