Wrong pricing on items and bad customer service

I went to Edgars Thabong to purchase a fragrance and had a good customer service from Mami except that she was uniformed about promotions in her department and that she had two name tags with different names. my biggest concern however is the fragrance I was purchasing witch had a different price tag from what was scanned on it, after I bought a lacoste which had a tag of R865.00 and reached the security to have my receipt signed we realized that there was a price difference on the receipts and went back to Mami who couldn't help me and called Lebohang who also couldnt help and eventually called \sister B "Mbali Nene and Mbali with her attitude also didn't want to assist me in getting the fragrance at the price that was tagged. everyone from the security lady"
