Out of stock repeating weekly

<p>Since the begining of the year ( 1 January 2016) my father goes every day to Checkers liquor in the Kalahari Mall in Upington to buy a liter of Three ships whisky and since the begining of the year EVERY WEEK Checkers liquor kalahari Mall Upington runs out of stock. He did lay a complaint by management and by the banch manager and every week they just apologize and the problem does not get resolved. And again next week with big dissipointment he gets there and agian there is no liter Three ships whisky on the shelf and so it repeats week by week.How many times do you need to complaint before management take you serious.</p>
