So I bought a hashrate contract from a fellow bitcointalk member recently, and since no one was responsive via messaging on the cloudminr.io site we transferred the account itself over to my control rather than simply the hashrate. I messaged them a few times over the course of approximately a week asking them to help move the contract itself as I didn't like having redundant accounts. After having not responded whatsoever for about a week, they updated their twitter saying they were processing all support tickets. The next day I try to login to my account only to find that it had been pulled from the system altogether-my email address was not even recognized.
A heads up to you all, this service is trash and I think they might pull an exit scheme at some point, so tread with caution.
I would not recommend giving them any of your bitcoins.
