That tone of voice

From an E-mail acknowledging payment on an auction I just won:   Hello, and thank you very much for your bid and payment. Your item will be shipped within 24 to 48 hours. It should arrived within 5 to 10 working days within the US, longer overseas. Please do not contact us asking if your item was sent, We can assure you it was. Kindly be considerate and keep emails to a minimun. Feedback will be given once it is posted for us. Again thank you for your payment and bid.   Yes, we don't want customers contacting us and having any sort of "relationship"...
