Once again totally disgusted & disappointed by poor service

I was once again totally disgusted and disappointed by the poor service I received at Woodlands Pick n Pay Liquor. On Sunday 08/04/2018 I was told they have no stock of cases of 24 bottles of Windhoek Lager. After speaking to the manager I was left furious. I cannot tolerate it when a manager blames everything else for not having stock and expects a customer to be satisfied with a simple “Sorry!” It reflects poorly on management for not ordering sufficient stock timeously. I expect more from Pick n Pay – Make a plan – after all you deliver. Tell me you will get it and deliver asap. Everyone knows a case price is cheaper than a 12 pack or singles, so I expect the manager to make a plan by offering me 12 packs or singles that are in store at the case price! Lack of stock is not limited to just this one store. I visited the Pick n Pay Hypermarket Liquor store on Sunday 2018/02/17. I requested a case of Australian Bundenburg ****** beer and was told there was no stock. There were several bottles of Bundenburg ****** beer in the singles fridge and I would have expected the staff to get an empty box and fill a case of singles. I was pushed around and verbally assaulted by staff when I suggested this and nothing came of my complaints to Hypermarket management or to the divisional manager of Diageo Field Services whose rep assaulted me.
