I didn't take his service.... But if you get $0.1 all other times then I think it's very fair.... These services depend on you to write at least 1 post every day... in that case:

$1.4 + (30*$0.1) => $4.4

That's the least amount you should get (which is probably isn't good enough)... But you must be active enough, and if you were active more you should get more than that.

That's how @blockgators sees the situation.... But I think the problem stems from not stating that the upvotes he gives are %5 in the terms (If he stated that in the terms and you didn't see it then it's your problem), that's why I wish he'd give you refund.

By the way, know that SP delegating services give less than that for $5, right? unless you use all the votes on yourself...
