Very bad service

This morning I went to Pick n pay Kempton square to buy pies for breakfast since the were on sale (2 for 32),what a bad service I got from the shop assistants from bakery I was never told that the pies they gave me were not sale.I was only told that when i got to the till, she(Hunadi Matibidi) kindly called the supervisorwhich i forgot her name,she also told me what the cashier told me (apparently the pies they ran out of pies at were on sale).

I then told her should have written a notice so that people know that they don't have stock..And she became dramatic by canceling the whole transaction (I also bought water and chicken wings)and said she is going to call someone who is going to help and the she came back with the lady from bakery to explain what she told me.. I then said to her that I had a query about the pies why was she dramatic and canceling the the whole transaction,she just told me she wanted the cashier to help the next client which I felt it was unfair ..
