You want a list of questions?

How many people do you have assembling miners?
Do you have parts for all the miners that have been ordered?
If not, are you buying parts piecemeal as you get more funds from new orders?
How many miners ARE YOU BUILDING every day?
Are you shipping miners in order of order numbers?
What order number have you shipped up to?

Do you see how answering some simple questions like that could provide your customers with actual information that would quell much of the anger?

Also, since you have lied numerous times about some of these questions, like when you said you were shipping orders in February, some pictures of the inventory of parts and the shipments of miners would help. You say you have enough cases for the next 500 orders? Mining PCBs? Take a picture of them, in bulk, from far enough away to show the total quantity.  You say you are shipping miners every day? Take a picture of a stack of outgoing boxes.

Simple!
