A rude/raw supervisor in customer service

I am not sure if this is how owing customers are supposed to be treated. On the 10th of December I received a call from a call centre agent. Poor girl did not have answers for me. The understanding me asked her to ask around in the office or ask the supervisor. The supervisor was confident to tell me that there is no Edcon store in Nicolway, Bryanston. I kept on asking him if he is sure and if he can check on the intranet but he felt big enough to tell me that I must go pay in Protea Glen since I stay in Protea (Soweto). To my surprise, I don't know who told this supervisor (Tebogo) that I have money at that time or if I am in Protea Glen to go to pay there. I was okay with the fact that they don't know where other stores are but when I asked him to check on the system he raised his voice and told me that there is no edcon store in Nicolway.

I was getting irritated at his confidence and telling me that I should do an eft or go to protea glen even though i told him that i will be in bryanston on friday and i can make that payment. My question now to the manager is: Do you put supervisors that are that rude to "owing" customers in those positions or Tebogo was just a name that they picked up? 1. I had to introduce myself and ask him what his name is even though I am fully aware that he can see all my details on the screen. 2. I had to make personal calls to other departments to check if there is any edcon store in Nicolway. 3. The rudeness of that man was way too much. 4. Don't these people have a system to check a closer store to where the customer is asking?

I hope these kind of supervisors are not what Edcon and Accenture pride themselves in.
