I'm not happy at all with the service

I bought a laptop at Game Trade route last year. In the 1st month it gave me problems. I took it back and they told me its nothing major. It worked for a while until it gave me the same problem again on 23rd of February 2015 at Game Soweto they restarted it and told me it will be fine. On the 4th of March I took it back to where I originaly bought because I was tired now of complaining about the same thing. The manager didn't help me at all instead he told me there is nothing he can do. I still have my proof of purchase for my warranty for repairs but no I was given the cold shoulder. A sales person felt sorry for me due to me stating I need to submit work so he said he would log a call for a technician to come see it. They said they will send me an email, where they mocking me because how will I get the email with my laptop dead. I haven't even received a call from the Store. Thank u to the staff that tried to help but the manager seriously needs to learn how to treat customers. I'm still not helped and never going back to that Store
