Edgar’s Rosebank Service

I bought a shirt at Edgars Rosebank, took it back and asked for a cash refund without my original slip but I had my eft slip, one of the cashiers could trace my slip on their system (through my EFT slip)and she printed the slip but the credit manager THEMBI came and advised that I can not get a cash refund and then called the contact center and spoke to Bulelwa, she advised that a cash refund could be done and asked the store to call her back, how can the store allow me to use my own phone inside the store to call the contact center???????? Where is the customer service???? I am really disappointed by the level of service received, your staff members Need more training on how to treat customers! They just ddnt want to assist me. It was a cash sale. I have an account with you guys and unfortunately I will be closing it this week, I am really disappointed.
