Dealhub doesn't deliver or respond

I placed and paid for order DH12805 which is for a ceiling fan control switch. Dealhub confirmed the order on 17 January by email and indicated that delivery will be 7 to 15 business days. The order was supposed to be delivered by 04 Feb at the latest but by 01 Feb I had not received any notification of the delivery so I wrote an email to Dealhub enquiring when I can expect the delivery and until today 09 Feb they have not responded or made a delivery.
