Email just sent to Pangolin.

Dear Sirs,

I am demanding a full refund for the my order as MicroBT has failed to meet the delivery deadline. The lost revenue alone is far more than any refund of delivery cost. Also, if all first batch units have been improved to 48TH/s where did they suddenly get the 44TH/s units to fulfil the orders? It is obvious they have been mining with them all along and doubled the difficulty with profits that were due their customers. This miner is no longer profitable. I will not order from MicroBT or Pangolin in the future as it is clear that they are not acting ethically towards their customers. Please remit the full refund to BTC address xxxxxxxxxxxxxxxxxxxxxxxxx
