worst service recieved as of yet

I purchased a car audio player on Thursday 20/11/2015 but would only have a chance Saturday 21/11/2015 to have it installed, upon taking it out of the box I saw that it was faulty, loose parts were falling around in it, returned to the store today 22/11/2015 only to be helped by a certain Willie who was rude and did not try to answer my questions or hear me out, all he just said no refunds for electronic goods, which at best I would understand if it broke while I was using it, which was not the case, I received it like that , in fact he refused just to me his manager or co worker was not there and he couldnt assist me,fortunately I read their return policies on their website and have worked for a number of years in retail. I really hope the people in charge address the issue because word of mouth is a powerful thing and in this day and age I dont think anyone would appreciate loosing customers to their competitors or in fact just loosing customers<br>
