Ace Hardware I purchased a well pump from this company and it came with warrenty that company did not honor. Shelby Township Nationwide

During the winter of 2013 my water pump froze and cracked it's casing.This pump I had purchased from Ace about 15 months earlier.It came with a 12 month warrenty so I was out of luck there but I purchased another and that one also came with a 12 month warrenty.From the day I installed it I had problems with the switch that was supposed to kick in when the pressure dropped to a certain level.After it refused to function correctly I contacted the companny where a very abrasive customer relations rep told me what I had to do to remedy the problem.I did as I was told but the problem persists and I have now had the pump about six months.Due to the manner in which  I was spoken to ( very rude and as I said abrasive) I do not feel that further contact with the company will reach any resolution.All I was requesting was a replacement switch for this $230 pump.
