Musica sells damaged goods...

I've purchase the family computer retro gaming console at Musica Mall of Africa on Friday the 30th of November. To my excitement, I got home, and set it all up. Disappointment arose when I saw that the system was not working. Saturday morning the 1st of December I took it back for an exchange as I thought that it must have been from at bad batch. They have assisted me with the exchange, got home, switched it on and again, the 2nd unit doesn't work as well. Okay, so I'm unlucky but the 3rd time is a charm. Sunday 2nd of December I took it back for yet another exchange. Got home and switched it on, only to find out that the 3rd console purchased from Musica is also damaged.

How does Musica intend in rectifying this matter and reimbursing me all my fuel for running back and forth as they sell broken units to the consumer???

This is extremely pathetic, especially coming from such a "reputable" store.
