Same here. Time to apply pressure from customer protection agencies and BBB.

I purchased a plan for my December batch miner on a time-limited offer in late November. Given that they were offering hosting plans so very close to the promised release date, either Cointerra knew they were behind schedule and didn't share this info with Terramine hosting, or Terramine hosting also knew this info and decided to quickly sell as many hosting plans as possible before everyone else found out.

I really don't see how Terramine Hosting /Cloud hashing is a different company than Cointerra except in the sense of it being a different administrative unit. The address on my bitpay receipt is the same as Cointerra, and the way they do business is the same as Cointerra. They promise refunds, and repeatedly come up with a very long string of excuses for why it hasn't come yet, with ridiculous technicalities, and delays.

Cointerra refunded me four months after I requested a refund.

I waited over four months since I requested my refund from Terramine Hosting, but have gotten nothing yet.
