Did you perhaps place the orders using a different email address? It may be that the orders are associated with another email address than the one for this account.
please contact the sales department at sales@webassist.com
or by filling in the contact form here:

In your message to the sales department, if you can provide an order number, they will be able to use that to look up the order and find the email account it is associated with.
