Even if you set your budget at a certain target and they hit it, you can expect to get more, I was hit with 100+ over the amount of the lead. They straight up told me the opportunity leads that I can accept will be bigger fee leads because I'm pausing and limiting my other budget. Once I put my budget lower the leads for really small projects that used to be like 15 bucks ended up being around 40-60. They are scamming you if they don't get what they thought they could before.
