Selling outdated Apple Laptops as new

I purchased a MacBook pro computer on the 23rd of January 2015.I paid R14999-90 for the product.(NOBODY TOLD ME THAT THIS WAS OLD STOCK)<br> During November 2015 I updated the operating system to the new OS X El Capitan operating system. Immediately after installing this new operating system I experienced various problems.One of the main problems was that my computer was noticeably slower in general.<br> I logged into the support site and noted in the Community Forum platform that almost every person with a similar problem had a machine prior to mid 2012.I then checked my computer's manufacturing date for the first time since I bought it.TO MY SURPRISE I NOTICED THAT MY MACHINE WAS A MID 2012 MODEL.<br> In other words, I bought a two and a half year old computer for the price of a brand new model.Please note that in this two and a half years the following models were manufactured by Apple:<br> 1.Macbook Pro 13\ Late 2012 <br> 2.Macbook Pro 13"Early 2013<br> 3.MacBook Pro 13\"" Late 2013<br> 4.MacBook Pro 13\"" Mid 2014<br> 5.MacBook Pro 13\"" Early 2015.<br> This means that I have missed out on two and a half years of new computer technology.<br> I believe that somebody must explain this ********** sale to me!!"""
