**** about product

I bought a Seagate 1 TB external hard drive today 24/05/2015. They Saleslady told me they only have the display unit available but it's never been used. I'm leaving on a holiday tomorrow so I don't have time to look around so I said that is fine since it's unused. It was then marked demo and I payed the new price which id fine, because I was told it was not used. When I got home now to check the drive I found three discs of mp3s loaded on the drive December 2014, meaning the drive has indeed been used. I also believe this is a copyright breach, meaning legal action could be taken. Unfortunately the shop already closed at 5pm before I checked the drive and tomorrow I leave the country for two weeks and I bought the drive to backup my photos and videos. I have no idea if the drive was previously used to play music in the store or how it was handled as I was told it was only in the display case
