Interesting. Try writing a post on their Ann thread here: https://bitcointalk.org/index.php?topic=2103097.20 and hope that you get a response. If not though then you just got ripped 0.7 BTC or so. Haven't heard anyone else complain about their service so it could just be an isolated case.

Though they have indeed ended their campaign after just a month or less. This is pretty suspicious why they gave up advertising so quickly.

You have wrote to support right? And no response for 2 days? Just keep writing to them and hope for a response, all you can do right now.
