Lowes has blocked my Dr lic for too many returns....the only problem is....I've returned items maybe once or twice in a few years. I told the manager I've spent thousands of $ at his store and he just laughed and said he has contractors that complain all the time.....he didn't seem concerned. He said he had absolutely no way to override the system.
I told him I would not shop at Lowes any longer and he was OK with that.
With the economy as it is....you would think they would focus on customer service. I had planned to spend much more than the amount that I would have gotten on the one little return. I called the 1-800 number to see why I was blocked and they have a recording saying to leave your info and they will get back with you in 2 business days. Again....great customer service???
