Now canal walk won't refund me on their expired chicken

<p>I bought 8braaipacks of fresh chicken from pnp canal walk last week. When I cooked it it smelled off. I checked the expiry date and it said the 08/08/2016. When I called the manager he told me he won't reimburse me or replace it without a slip. I even told him I'll bring the food I made so he can smell it and he laughed at me. Gave me attitude saying they won't sell expired chicken and spoke to me like I was stupid for even suggesting that I bought it at the store. When I threatened to put them on hellopeter he tells me I should go ahead and do it if it makes me happy. Pathetic service and attitude from Thabo the so called manager! </p>
