Yeah brother, just think of it as you paying $90 to get a really good lesson. Now you know. Some creators are fine (men/women), and some creators are dogshit radioactive (men/women). Creators and customers both think the other is out to take advantage the them-- and probably are.
A pro-tip I've found that works SUPER well when dealing with slightly misleading or slow-responding creators is to NEVER show signs of anger or frustration when dealing with them.
Often times when I'm trying to get something from them, and they seem to be fucking around, me getting upset/snippy just scares them off and I'll be blocked/ignored. These folks have no sense of guilt. To keep your chances up, stay strong, stay friendly, and focus on the goal. ~Getting what you want is what matters~; Airing out your concerns/emotions on them does NOT. And well if you think they're never going get you what you want, just leave em alone and cut your losses.
Maybe 8/10 when I'm working with an inconsistent creator does this tactic work tho and I get what I want eventually. Stay persistent, friendly, and don't over-message them. Goodluck brodi.
