Bad service

I have been experiencing bad service from delivery guys from Deboniars Pizza Maponya Mall. During the delivery process i asked my son to go pay. My son can and said the guy doesn't not have R10 change. I went outside only to find out my delivery its free because the dot was black. I told the him about the policy of free pizza. I asked him to call his manage he refused ,he left my money on the pavement and left. My son wanted to pick it i told him to leave it there . And decided to drive to the store and explain the service i received from the guy and demanded my money. Manager by the name of Sarah said they will attend to my request once hey hear the delivery guy side of the story. Even today am still waiting . The black dot and red policy doesnt not apply at SOWETO its only applicable in the suburb.For the delivery guy to leave my hard earned money on the pavement was very disrespectful.
