Alberton Matrix Warehouse refund.

So Matrix Warehouse Alberton I order a specific computer fan with a specific fitting for a computer originally purchased at Matrix Warehouse. Send you photos and part numbers of everything on it. I kiss your ..... a few times reminding you about this. Then resend all the above as it was misplaced. You invoice me and I pay immediately. Eventually the part arrived and my Mrs fetches it. It clearly the wrong part and definitely the wrong fittings. You explain well you thought it would work. Now to get a refund of the money I paid I have to jump through hoops and draw square circles. All for a part you incorrectly ordered for a computer I purchased at Matrix Alberton. Your service explains why a once mega store is now a dismissal store in a shopping centre. I don't have the patience for your s@#t so will write off the money to school fees.
