Selling secondhand phone as new!

Newmarket Branch, 5 May 2016. Purchased a Redmi Note 2 phone for R2 699. When I opened the package at home I saw that the battery was already installed. I went through the set up process and after that looked at the file explorer app. It highlighted some PDF documents and music files on the device. I then looked at all the folders on the device. It contained a Whatsapp folder. Inside this folder there were Whatsapp profile pictures and message pictures. I immediately returned the phone, first they tried to locate a 'new' one but was unsuccessful. So I refunded. So two mayor issues: 1. Selling old phones as new phones, utterly unbelievable and despicable. 2. Selling these 'used' phones with user data still on it! So much for your privacy. I am disgusted, thank you for wasting 1 hour of my life today with this despicable way of doing business. Customers must beware because they have no idea what you are actually selling to them.
