Almost poisoned by liquor city buffeldoorn klerksdorp

I made a purchase at liquor city klerksdorp buffeldoorn road only to find that the liquor was expired one year and three months ago (17/06/2017) it was revolting left a bad taste in my mouth but as return to the store the cashier was unapologetic and had a bad attude toward me saying that she has only been working the a week so it's not her fault so I asked for the owners number but the number did not work I could understand if it had a month expired date but a year and three months disgusting shame on you customer service none.
