It's obvious, sir, that you are clueless
You put their banner in your sig for one reason only: To win one (or more) of their cash prizes.
You don't get yours asap and, like anyone would do, inquire. When you don't hear back in good enough time you then started acting like a whining ten year-old.
You keep their banner in your sig but also slag them with the non-payment text below it. You post in a "webcam sponsor" thread and note that even though they haven't paid you, you still like them.
You then start a thread crying about the whole thing and making yourself look like an ass. All over, what, a $100?
Dude, is business that slow for you? Are you so incompetent in this biz that $100 is going to make any kind of difference in your monthly income? Oh, I see, it's the "principle" right?
Okay, here's some principle for you: Don't publicly fuck over the people you are trying to win money off of in a contest. This is their livelihood and you are doing your best to give them a bad rap in a public way, all the while defending your actions with nonsense.
Grow up, be a man, be professional and remove that shit in your sig. They will get back to you and you will be paid. And then I suggest you find another line of work, apparently this biz isn't right for you.
So, a gift (and subliminal hint to you):
