Review They robbed me at Naas Kamaqhekeza Exact

I went to Naas Kamaqhekeza Exact to buy some Athletics jockey vest which were on special from R250
To R239.99 then it said on the outside cover box you'll buy 2 vest then get 1 free so I went to the till to pay and I asked the lady wear's the other free vest she said there's no vest yet it says on my slip it's a promotion for 3 vest then she said it'll be R250 I said how cause there on the price tag it's R239.99 she said It went up I was surprised now when I got home when I found out that those vest were supposed to be be 3 ... and I want that R10 back to me cause she lied to me her name is Nqobile Khoza from Kamaqhekeza Naas Exact
