No replacement for broken Macbook charger

On the 3rd of January 2015 I purchased a Macbook Pro 15'' inch from the iStore Pavilion. Not only has this laptop been a complete disappointment as it has had so many crashing/software issues, but the technical staff at iStore pavilion are completely uninterested in your problems. I took my laptop in a couple of months ago for a crashing issue. The technician was so rude and spoke to me as if I have no idea about computers. He also told me he would back everything up but didn't- I lost everything. Anyway, this incident isn't the reason for the complaint. It is now the 28th of Feb, and yes technically my 1 year warranty is finished, HOWEVER yesterday my Macbook charger stopped working so I went in today and they told me that there is no way that the warranty will cover for a new one. I am so annoyed that it is honestly only about 3 weeks after my warranty is finished and my charger stops working. I have taken such good care of it but the quality is so bad it stops working after a year. They are not interested and tell me I have to buy a new one for R1700. That is insane. I spent R27 000 on a laptop and the charger cant even last more than a year. I am so so disappointed with Apple.
