swiss company binary options would not return balance of $250 after it had been approved Internet

I joined this Co. on Oct.8,2014 for $250 with understanding that it was auto trading.  The robot wasn't working , so I e-mailed them and they said they were working on it.  I waited until Oct.13,2014 and it had made 3 trades. I requested withdrawal of my balance, which was $250 (I tried a few manual trades) to get balance back.  Then I requested withdrawal of my balance, which was approved.  I was told by e-mail that I would get $200 by end of week and $50 by end of next week.  I have not received anything. (Nov.3.) I have tried numerous e-mail and phone calls, to no avail.
