Pathetic service Pick n Pay

On the 27th of June 2021 I went to pick n pay Randburg Square. I bought 12 packets of 2,5kg snowflake cake flour. The birthday special was that if you buy 4 X 2,5kg you get snowflake baking powder (200g).. There was only one packet in the shop. I waited for over 10 minutes while they were looking for the baking powder. They had the audacity to say I should come daily to see if they have the baking. I told them that was ridiculous they then decided to take my numbers. To date I haven't received a call from pick n pay. How does such a big company advertise something that they can't keep up with

Appalling service from the Randburg Square.
