disrespectful consultant

I made an application for rcs credit through makro. an automated email pre approved my application subject to docs that must be emailed. i emailed my documents and no response was received. I went in store and was put through to the call centre. I spoke to Thembakaze who gave me a different email address to email my things to and she assured me she will help me because i was in store waiting. No response after that. called Thembakaze the next day and what a rude person she was. speaking over me and being sarcastic. She told me she didn't make any promises to me when i was in store. She didn't want to give me her name or a reference number. She was shouting over me on the phone and making me out to be ****. If that is good customer service then the call centre should closed. i have never been treated like that before. I will never shop at Makro again. yesterday was my first and last time. totally disgusted!!!
