Hi I had emailed about a previous order of this same product in which one or two of the lights weren't working. I did like the product and did order another set but them I was emailed saying that I would be sent two of the lights sets to compensate for the one that was broken. I see a charge for one set of lights but was under the impression I would receive two sets (one free and one paid for). I received only one set. Attached is the picture.
