They are useless-so disappointed

I am trying desperately to get a hold of a product which Pick 'n Pay Centurion continually assures stock of. I was referred to Centurion as my local PnP didnt have stock, and the online system and Centurion manager confirmed Centurion did. After having booked a qty of 50 products, I drove to Centurion the following day, to discover thay had 'misplaced the whole box' (according to the manager herself). Everytime I call I am bounced around from department to department, often lose the call, and am assured someone will call back once the stock on the system is located in their warehouse. I have been trying for over a month to get this stock . Head office has not helped at all and has meerly referred me back to Centurion. I am actually gatvol with this terrible service which ha left me with no options and still no product.
