I am waiting too for a full refund of 10.471$ about my order  SX7002 on Cointerra.com and  #831 on terraminehosting.com.
There are past over six weeks.

If I do not receive a refund in 7 days I'll proceed through legal action.

We are all entitled to be refunded.  Let's just hope cointerra do not disappear and do a go on us. They have been ignoring refunds enquiries for a while now
