Defective Item

I bought a laptop at crusaders Maitland , firstly it wasn't an i3 laptop as the lable in store says.

It was an intel celeron laptop and we only discovered this within in 7 days

We also discovered that the right click button and some other keys dont work and then thing takes forever to load.

We went to the store and they refused to give a refund and it was on the 6th day.

This is very unfair as they sold a defective item and then the manager took her own initiative to send it away for repairs , i never wanted that, i qualified for a refund.

What am i supposed to do with the a laptop now , i cant even sell the thing.

This is very poor service and i am not gonna let this stand.
