Pick n Pay Brits Mall bad service

Today I went to Pick n Pay Brits Mall and I was told in a rude way by the frontline leader that u can get Cake for R120 with Coke only...I asked her to go and check what was written on the promo as it was written that you can also get another drinks and she refused telling me to get Coke or nothing. The service @ Brits Mall is really going to the dogs lately.
