Poor Service @ Elna Cavendish Square

I was assured when I took my sewing machine in for repairs, that it would take 1 week to fix. It was finally ready to be collected 3 weeks later. I was quite excited to use it again, only to find that the light bulb was now missing. I phoned immediately to ask where it was, and was told "It probably broke in transit, and the repairer probably didn't have any spares". Well, I have moved house 5 times in the last 10 years, and it has never once broken "in transit". Makes you wonder how they treat it "in transit"? The next week, I took it in for them to put in a light bulb (I have never broken the light bulb before, so didn't know how to change it myself) Blow me down, if they didn't charge me for the light bulb that they broke?? The owner of the shop, was sitting there, and didn't bat an eye lid!! Didn't even look embarrassed?? I wonder if Singer does repairs to Elna machines? Definitely not going to try Elna ever again
