I sold a PS2 with a spare controller, they were all in the original packaging and were never heavily used. The buyer says that they have arrived and the PS2 is in 'immaculate condition' but the black controller doesn't work properly.
I don't sell that much on Ebay and I have never had anything not work before and so I am not sure what to do now. Do I ask them to explain what is wrong with it and then ask them to return it or give them a discount ?
