No rseponse to emails or call centre complaint

I purchased 7 items from Boardmans online. Despite the website saying it would take 2 - 5 working days for delivery, it took 11 working days. To my surprise only 2 of the items were delivered. There was no correspondence with the delivery to say why the other items were not delivered. I sent an email on the 18 Jan to ask why I did not get my full order. I received an automated response saying that Boardmans customer service would contact me within 24 hours. I still have not heard from them. I sent a follow up email on the 25th Jan and got the same automated response. Once again no one bothered contacting me. On the 29th Jan, I called the Online Customer help desk. I spoke to Steve. All he could tell me was that the items were out of stock, but did not know when they would be getting stock in. He told me that someone would contact me on the 1st Feb to inform me of when I will get the rest of my order. I still have not had a call from anyone at Boardmans. Very disappointing service!!!
