Dreadful service

I ordered a presser foot from this company, I didn’t hear anything from them for two weeks. When I emailed them I was told the order had been shipped. It eventually arrived but it was not the same as the one I had seen on the website and does not fit my Bernina machine. I have since emailed them twice and filled in their online return form but have received no response. I am currently out of pocket to the tune of £30 for an item which I cannot use. DO NOT ORDER ANYTHING FROM THIS BUNCH OF SWINDLERS
