Empty promises and unprofessionalism

I was livid, angry and very much disappointed at the Woolworths Sandton City stuff. So I checked online for a Rich Mnisi black jumpsuit then decided to call Woolworths Sandton City to see if they had it in stock, I was transferred from one rep to another whilst they were trying to figure out what I was looking for. Finally one lady assisted and didn't mention her name, she then said she'll reserve a size M and L for me and I told her I'll fetch it the next day,she then took my details. When I realized they close at 8pm, I then decided to drive there and go fetch it. To my surprise when I arrived, no one had a clue what I was talking about,I then decided to show them the picture of the jumpsuit(which was on your website) . They checked on their system using some code and I was told it's out of stock, noone whatsoever cared to assist and try find out who reserved the item for me. One lady then told me that it is on sale and they don't reserve items on sale. M question is, why was I not told over the phone when I wash promised they are reserving it for me? I travelled all the way from East Rand, late at night hoping to get the jump. Mind you if I didn't reserve it,I wouldn't have went!!! This is just a pure indication of incompetence from the stuff!!!
