Bad service and treatment of customers

On Friday 11 January I went to Woolworths Village Square in Durbanville to purchase a soft drink and bread after paying for my goods I walked back into the shop with the goods that I purchased I then realised I had to little money so I started leaving the shop I was then blocked at the exit of the shop by 2 female security guards one behind me and one in front asking me for slip of goods that I had already purchased which I showed and the cashier had also told them that I had bought the goods there I find this unacceptable as I was stopped like a ***** at a shop that come to everyday and previous occasions when I walked into this shop have been followed by security. I felt traumatised and humiliated at the way in which this matter was handled by security and management and will be putting this up on every social media platform
