Undermining customers

I visited Newtown Junction Shoprite to purchase a few necessities for my 2 week old baby.. Now as you can imagine I am not fully recovered ,but no one else can go on my behalf.. What bothered me was the way i was being followed around the store as thou i was there to ***** ... I personally regret having put some money away for this time using Shoprite gift cards ... the way they stood at the door and searched us wen we left was just sad .. ive never felt so humiliated... I personally will never visit a Shoprite store ever again... How can I spend almost 1000rand n ***** at the same time..? No ethical sense... its totally appalling..
