I still can't grasp my head around KnC's latest sales decisions. Why would you sell now a controller board when just a few months ago everyone would have given everything for them? Same for the upgrade boards. Unless they plan to unload their whole datacenter jupiters to replace them with neptunes. I can't think of any other reason right now.
You answered your own question, everyone wanted them, Including KnC. They ran out of space adding modules to peoples hosted miners to run on the side for themselves and then kept all the control boards for themselves and set up a large data center, probably using November boards, which will be dismantled and sent out to the original hosting customers before KNC deploy their 20nm product in the data center, which the probably own a large % of due to refunds, but it's okay because the mining facility paid for that.
The number of people that wanted them back a few months ago was very small compared to the number of boards they needed for the DC so i don't like this argument. If they were selling controller and upgrade boards only for their previous customers i don't see how that could impact them so much.
Edit: I'm not familiar with what paperwork has to be filled when making a refund for an order that was filled with tax authorities last year. Anyone care to share some details about it?
Edit2: On 11 April i made my request and they told me 7-10 business days in the e-mail. If we don't count the Easter Bank holidays then on 29 i'm at the 10th day.
Here is the history:
11 April: "Thank you for the update. Your refund will be processed shortly. "
17 April: "The refund process usually takes between 7-10 business days. Our finance department are extremely busy at the moment but we hope that you will be refunded shortly.
It seems that mining 300k-500k$ per day can't get you a good finance department.
