anyone work of ad-center – they don’t pay me

I work with ad-center about 30 days and make a payment $ 485 about 2 month ago, but unfortunately they do not give me my payment. i am already contract the manager but he give me un-nessary excuse (and not send my payment). Dont work with them, they cheat, advertise with being untrusted sponsor and not paid – a one-way road 🙁 this is scam company)
