BAD Customer Service

I purchased goods at Parow Center on 1/2/16 to the value of R127. Whilst standing in the Que, I saw a sign stating purchase more than R700 and receive a free watch, i asked the cashier about the watch promotion which his colleagues assisted with, they gave me a black and a pink watch to choose from, i the asked why does it differ from the picture shown on the advert, the girl counting money at the next till (Cynthia) then told me thats all stock that they had left which i accept and was trying to decide which one to take, she then asked which one and i said Im still deciding, NOT even a minute later she said to me \Mam, have you decided, there is a que of people i said to her i am still deciding and that i don't care about the Que and that she should avail herself and her till for the customers but moral of the story is that they never discounted this \"Kiddies\" watch, they charged me R199 with a R37 discount. I then was in N1 city to enquire where the manager advised that i should go back to Parow center to inquire as they couldn't assist me, i then did that, spoke to Lindi which was also giving me a run around. All i want is the correct watch to be ready for collection at Parow C"
