Guy on sextpanther came in 30 seconds even though I have a 5 minute minimum, is he trying to scam lol?

He came in literally less than 30 seconds lol. Of course it asked me if I wanted to refund the call, I said no cause it’s not my fault you spent 45 dollars to cum in 30 seconds… is this a common scam on sextpanther, similar to guys yelling at you to undress as fast as you can on streammate so they can see you naked before the 30 seconds is up in private?
