Being terated like a convict at the store

<p>i bought refreshments at Engen Midrand, and got into a heated argument with the staff, on your promotion you had the 87g bubbles slab of chocolates on promotion 2x87g for R33.00<br />on the same shelf, there's the 87g of chocolates plus 20% free.i'm laying emphasis on the FREE part.Now, i don't know if your employees lack the basic knowledge of math, or your marketing department don't understand the part where your advertisers promote FREE on their items.i eventually gave up, took the 87g of chocolates and left, when i got to my car i got accused of *****ing the second item, i tried explaining to them that you get 2x87g of slabs and not one, after they saw they were in error they left me alone, i've been treated like a convict, and been publicly humiliated in front of other people.i'll never ever refuel my vehicle there again,EVER</p>
