Bad service

I sent someone to take my Samsung Galaxy S4 because the battery was swollen and couldn't fully charge anymore. I started using this phone in January and on their website it states that the battery's warranty is 12 months, but the guy working there wanted to sell me a new charger for R250.00, saying that the battery's warranty is 6 months. <br> Sorry, but how can they sell a phone with such bad batteries? This is terribly ripping people off. Not many of us can afford to buy things every time. I am not happy with Samsung.
