Doesn’t give credits you paid for

I don’t use this app. I paid for 499 for credits and still haven’t received them in two days. No response every avenue to get a hold of anybody is a daddy and you can never actually talk to anyone not even a recording so no don’t use this app. Developer website is fake The email does not work. The telephone is a dead end. Text messaging nowhere..
