Arguing with a customer when they ask you to speak

I'm Not sure where you get your call centre agents or supervisors from but would seriously suggest you send them on proper training courses on how to treat customers... On speaking to an agent who started to argue with me when I asked her to speak clearly so I could hear them to a call centre supervisor who also started arguing with me..... when I requested to speak to his manager... Pathetic I am still waiting for a call from his manager who was conveniently not available...This is the second instance of this abuse that I have had to put up with from MR Price and will be closing my account with you. Done Klaar I am sure that there are many retail outlets that will treat me with the respect that is deserved as a customer. Or do you not give respect???? and just demand unclearly I might add....?
