Review Faulty device

I bought a printer last week at courts in port Antonio. Went home, opened the printer set it up and went about installing the driver onto my computer. I use a macbook pro which is up to date. After many attempts and checking the canon website, there was no driver that was compatible with my laptop. I returned it to the courts store and I am being told that my money was wasted because I would not be able to return the item to get a printer that works with the laptop because the package has been opened already. The printer is of no use to me and I am unable to get back my money to buy another one. I need help. I have bought many things from courts and i have only now returned with a product that I am being told cannot be returned. NO REFUND, NO PRINTER!!!
