Customer service

I walked into checkers Longbeach and saw that the cokes was on special for something like R12.95. I took 6 off the wrack and proceeded to the till with some other goodies. I was then told by the cashier that the manager then said its only 4 per customer, I proceeded to ask them to call the manager . The manager by the name of Sieraaj came to me and ask what the issue was i proceeded to point out to him that he had no sign of the limited quantities at the wrack with the cooldrinks. He then whipped a pamphlet out of his pocket stating and showing me that at the bottom it says limited quantities. I told him I do not walk around with a pamphlet and totally randomly bought these cokes and there was no limit displayed at the cooldrinks. He then just kept on showing me the pamphlet, again i said i do not walk around with a pamphlet i came randonly into this store, i advised he put a sign at the cooldrinks and he just ignored my remark and said its only 3 per customer ...contradictory as the ladies at the till said he said 4 per customer.I proceeded to tell him but you don't have a limited sign at the cooldrinks he just kept on with showing me the pamphlet, i then just said i will pay sepa
