Rude Agent for a fault that is not mine

Edgars failed to collect their debit oder,was called by a very rude consultant who just wanted me to pay and did not listen to me explanation.This girl was literally shouting at me.I called and told my story ,requested a team leader to listen to the call and get back to me and pls tell me if that was the right approach.No body has called and the next day called again made the same request and still no one is calling me.I later spoke to a lady who told me their debit order were faulty,which is making me even angry because it was not even my fault.New management but ****ty customer service.Even a fool knows the impact of bad customer service.I hate the store so much because it means they agree with the poor attitude that lady showed.I will write these email until the reach the CEO of edcon.Funny how I told the story to another agent and did not log my query and only wrote that I was just changing email address.I have never been so disrespected in my whole and have worked in the retail space for years .
