I don't think you understood, I paid 17.2 ETH directly in pre-sale (that pre-sale was posted on viberate telegram) and I've got nothing so far :S
Sorry, but there was no pre-sale. There was another phishing channel on Telegram with the same name and logo where the scammers were impersonating the real team members. I was almost scammed myself, but sensed something phishy soon enough; then I found the real channel.
Did they give you the address in a personal message?
If they followed the fake telegram link from the official slack channel then the viberate team should be held responsible.
