I bought a battery for a Dyson vac. It didn't work properly. I told the seller and they said I could return it. I tried the vac again before returning (it had been on the charger for a couple of days) and it seemed to be working fine now. I decided not to return the battery. After two or three weeks it stopped working again. I told the seller I would now like to return it but they responded with a simple 'This return is closed' and no other explanation. I tried to 'Ask eBay to step in and help'...
