Happy but unsure 😏Shelves/nets

Delivery was well executed. However the (sml) shelves on wheels that I ordered was discounted by R100 the day after I ordered it. Also I wanted the large one but it was not ava, was suddenly ava the very next day. Also the mosquito nets/screens that I ordered, I cannot use it because the magnets supp**** are hopeless, not sticking. . Not sure what to do about it as I am a new customer of Snatcher.
