Bad service

I bought a component system 30 november 2017 at hifi corp polokwane. Now the one speaker stoped working. I took it back and they told me that the one year warranty of the system only covers the amp not the speakers but they did not state it to me the day i bought the system. The lady had a huge attitude and told me she will see if they can fix it. How is it possible to sell something and when it breaks a month and half later they dont want to replace it and will see if they will fix it. I will never go there again because what is the use of a warranty if it doesnt mean something and what type of service is it if you dont even want to help out the customer that paid R5000 for something? Poor service. Will make sure everyone i know knows of the service and that they dont explain to you how your warranty works and that it doesnt mean anything. The customer service lady order the manager around. After he asked her if they will replace it she got hiped up and said very loudly that she will send it away and see what happens.
