I had a counter, sinks and faucets installed in August, 2020. In November 2 stains appeared on granite surface. I first called salesman who sold me top and told him problem. He replied that he had never heard of problem and would get back to me. He never did. I have been calling your store multiple times and your people have come to house to take pictures and try to remove stain which was unsuccessful. I have been told I was to blame, I lied, and various other insults. This has upset me so much I am now ill from stress. I am tired of being told someone will get back to me only to have to make repeated calls again. If I do not hear anything within the next few days the only option for me would be to call and attorney as well as post my problem with Lowes on as many community web sites as possible. I have always used Lowes and can't tell you how disappointed I am with your service
