Lights Out On Pre-lit Rotating Christmas Tree?

We bought a pre-lit Christmas tree that rotates, at Sears on clearance after Christmas last year. The lights have a 1 year warranty; the tree 3 years. A few weeks later we took it out and put it together to check it out and discovered the lights not working on a whole section. After many e-mails and pictures sent to the company it was determined the set of lights was not holding in the control box. There was a little white plug-in thingy not holding on the wire. They sent us a new set of lights that now hold in the control box, but there are still 2 branches on another row where the lights don't work that was indicated on the warranty form that I completed. The company never addressed this and they stopped responding to my e-mails. After realizing how difficult it can be to replace the lights to be like they're done at the factory, I requested they replace the lower section of the tree since the faulty lights are all on this one section, but got no response. I don't believe a regular set of lights can be used if we want the tree to rotate. Anyone else have this issue?

I did go to Sears and talked with an assistant manager about this issue. The man was not interested at all in my report and told me the best they could do was give me extra reward points which I turned down. I also wrote to their headquarters, but of course heard nothing. This tree was on "clearance", but still a "new" tree in its box! Now I wish we had asked to purchase the floor sample! I'm planning on checking to see if Sears has another identical tree to this one this year and demand they exchange it, but I fear that won't work. Needless to say, we are done purchasing anything from Sears! Customer service there is the worst! It's no wonder they're not doing well. Sad they don't see that.
