Mr Price sells not supported products

My wife and i purchased bedside lamps from Mr Price Cavendish Square, when we got home i noticed that the lamps that are required are bayonet miniature. The next 4 days i looked for these lamps and i couldn't purchase them anywhere, the feedback i was receiving is that they are discontinued i could only find the ***** in type. I then tried calling the store, but no one answers the phone, so i couldn't get any assistance with the problem.
