Extremely poor service on returns and communication with OneDayOnly

Extremely poor service returning products. A request to return an unopened product was made on the 17th February, all relevant paperwork has been attached to the product and customer services acknowledged this. The product has not been collected. A number of email requests have been emailed to customer services but there has been no response. Following this I've tried sending a message to the customer services through the web site itself and received a further email to prepare the product for collection. I have emailed once again but no response and still no courier to collect. THERE IS NO PHONE NUMBER for this company and cannot be reached to speak to someone to arrange this simple process. Today is the 11th March and still no response, the product is still waiting for collection?
