A 2 Z Signs

Review: Lights installed on fence and building 1/9/14. Given a two year written warranty for these led lights. March 2014 we called to say that some of the lights had failed. We were told they could and would be placed but needed to wait few weeks due to shipment coming from China. Now 80% of lights are not working.Never came to install the lights. We have been calling for 6 months to remind him that the lights have not been replaced. He now tells us that he is too busy with new jobs and we will still have to wait. He stated the lights were defective. He will not come repair or replace the lights. When pressed for a date he said that he can't give us one even though we have been waiting 6 months. He said that we could sue him if need be.Desired Settlement: We would like a refund or for him to replace the defective product he installed since we have already waited 6 months.
