You are assuming that everyone is just asking "where is my order". When I contacted them initially it was to ask about shipment and to purchase more equipment.

There is a multitude of questions that would require being answered by the seller for the purchase to be successful.
Here are some examples:

-If someone initially asked for an item to be delivered at address A. but afterwards needs it to go to address B. The person sends a mail to the seller asking for the change but doesn't get any response. The package is sent to address A. and the buyer isn't able to communicate with the seller, doesn't know if the package was sent or not etc.

-If the buyer marked the package for pick up but now wants to change the form of delivery.

-If the wrong item was purchased by accident and needs to be changed to the correct one.

I can come up with a couple more reasons why they should be responding to the mails in a timely manner instead of just ignoring the mailbox completely.

Edit: I just got a mail from technobit saying my order is being shipped. I just called the police to put the charge on hold until I get my order.
