Make sure when you return something you make sure ...

Make sure when you return something you make sure you document everything. This company won't refund $250.00 for a compressor I returned because somewhere, somehow in the return process I clicked on 'core' instead of 'compressor'. The supplier does not open the return package, they only read the label. I actually finally got through to the president of Rock Auto. He stated they couldn't give me my full refund 'because you cannot expect us to lose money'. So, I bought a part for $250.00, it was wrong, I bought the correct part for $635.00.....so, to understand this, an old woman who works three jobs just to stay above water should lose $250.00 because I certainly wouldn't want a multi-million dollar, world-wide company to lose it. All because a label said the package wss a core and not a compressor. Very sad.
