Sherwin-Williams

This morning, my husband bought a gallon of matching paint and when I tested it on the wall it didn't match, it was just a shade lighter so I brought that paint back to the same store that my husband bought from, when I got there, tom and the other 2 lemployees ladies were there too and have no other customers there. Tom asked me what I needed? I told him that I bring the paint back if he can rematch it to a shade darker, he said so rude to me that he not going to do that but can give me back the refund and he told me don't come back! I told him that I didn't say that I want to get refund then he rudely said back to me (I said that!). This manager is so rude, unrespect and we think he's race. My husband said this is not the first time but so many times already, he was so rude to him every time he was there.
