Edgars Online Item Missing and No Customer Service when enquiring

I purchased a twinpack pillows through Edgars online and when it was delivered, the pack only had 1 pillow in it. I immediately phoned the Customer Service number ********** 925 and reported the missing item. They said it would be investigated and someone would phone me back. 7 days later, 3 phone calls later to them and still no-one has given me any feedback for the item which was paid for in full and is missing. My last phone call to them on the 7th, I was told that I would get a response within 48 hours and the matter would be escalated to a manager. Still no response and its 48 hours later. This service is appalling.
