Wow what an interesting post. I bought from a company on EBAY called Fatrodders. I ordered a coolant overflow tank on a Buy-It-Now. 3 days later is showed but was not the one as shown in their picture. They had a phone number on the shipping tag. I called and explained and they were very apologetic. I asked how do I return the wrong one. The girl stated "Don't worry about it. Keep it, the correct one will be sent out to you today"
2 days later the correct one showed up
Super Customer service. I have ordered from them again.
