If your payment was sent manually, that is via some other method than an online credit card or online check payment, we may not have received it yet at the time that the notice was sent. We send reminders precisely for this reason, to ensure that you are aware of your account status.
In the event that you feel your payment should have already been received or cleared, please open a billing ticket in myCP (http://mycp.nanoservers.net/) or email billing@nanoservers.net with your invoice number, the method of payment, and any other details you can provide to help us investigate. We will follow up with you as soon as possible.
