Huggies without Huggs

Today I went to Pick N Pay Vaal Mall to purchase Huggies which were on special at R129 per pack. After much attempts to obtain stock, the store told us that they are out of stock. How is this possible? The add states sizes 1 to 6 but there exist no size 6 at any of the stores in Vanderbijlpark. They are all sold out??! We must be living like kings If all the kind wears size 6 nappies that they are all out of stock!!! I am utterly disappointed not only in the store but also in Huggies the brand. As a retail company they should have a service level agreement in place so they can see what stock is not in store. Either the stores counts are wrong or Huggies is pulling wool over our eyes. 3 stores and all of them are sold out on nr 6 nappies!!!! Is that not just too convenient????? I am shocked that such a well know brand could be so picky to have us go up and down not just wasting our money but also our time.
