Very rude service centre consultant

I called to find out about the call that was logged regarding my Defy fridge that is not working for 3 months now and the consultant asked for my for my invoice number and I told her I don't have it right now and she can call the store to find out as I was still busy talking to her she just put me on hold and when she came back she asked me who was I and I told her. I then told her it was rude to just put someone on hold while they still talking without letting them know she therefore said she did and I told her I wasn't deaf she never did and she went on to make a funny sound like pssssss at me at me. I am not very happy with this as a customer I personally feel it was rude and unprofessional of LOGAN GROUSE to speak to me like that as a customer. I need to be contacted regarding this otherwise I am going to the newspapers. I need an apology from her written and a call regarding this. Your speedy response in this will be highly appreciated.
