Worst experience ever!!!!

Went to Edgars bellville to check on their shoe specials since I ddnt get sizes in tygervalley with a friend . We had shoes from edgars tygervalley but unfortunately my friend had left her receipt at work. On our way out , the security searched our bags and found edgars shoes from tygervalley branch. The security lady was rude, acted as if she was sure the shoes were ******. We were stood at the door whilst the security was calling the controller which was more embarassing but we waited. The controller came, she was a lady, tried to explain to her but she ddnt want to understand. She was even worse than the security. She even involved other shoppers in store in this issue which was worse embarassment. Gave her the shoes to scan to check if it was theirs. When she came back, I was on a call with a colleague trying to get them to check and fax the receipt . The controller came back , demanded i was making a **** call to spite , swearing at us badly in english and afrikaans too, calling us names, getting in our circle and taking it to a personal level which she denied after I told her that she has no right to swear and treat customers in that way and I was definitely going to let this experience known. She found out that they didnt even have stock of those kind of shoes. I will never go back again to edgars bellville!! Please improve customer service and problem solving s****s. They really need a lot of training!
