broken promises and bad service

I purchased a grafton everest lounge suit cash, no terms and conditions was explained to me however after going through the booklets which was handed to me after delivery,i realised that for thr price and a well known brand the guarantee on the lounge suit was.not exceptable at all.,I then decided to return it within the 7 day money back guarantee period ,i reported this tp russells and there guys where sent to check the goods and pick it up,i then questioned about my credit as I had paid cash I was informed that after 3 working days money will be given back to me.3 days has been over the manager Sharon who is absolutely rude and screamed at me when I did go back for my money,she said the store does not have enough money and that she willl contact me only when they have money.On going there again coz I have not heard from dem with even a phone call, Sharon the manager is on leave and the staff lionel, des and the credit supervisor was extremely rude as all they sed was dey cud not help me and mocked even ignorrd me and sat in da office having lunch n discussin me,i will not except unexperience ppl like dis with pathetic service
