Makro Online shopping

I'm not Impressed with Makro online store, I bought an airfryer last year which caught flame in two weeks and I had to wait a month for collection for the return of the order. I then proceeded to buy a car radion in Jan that stopped working in a week...to date I'm calling back and forth for collection which was scheduled and no one collected it, the service is ridiculous and frustrating...I am now at a point where all I want is a waybill number for this return and no one is willing to assist instead my request is being escalated every 48 hours when I call the makro online department service centre
