AutoZone is FAULTY. Don’t waste your money with them!

I used to by most of my spares to service my company vehicles from Autozone. But from now on I will not support a single Autozone nation wide. I purchased shock saddles from them on Thursday 02/08 on 08/08 they will not take them back are their supplier won’t allow the credit. What Bull**** is this no company in their right mind won’t take something back especially when it has only been 4 working day! Utterly disgrace and a faulty business policy. No such writing is in their invoice either or disclaimer. BEWARE OF THIS FAULTY GROUP!
