EXTREMELY BAD customer service and poor quality of item

I have phoned homechoice 4 times in the past week to report that the almost R20 000 bed that we bought from them is poor quality and that the stitching has already started to pull loose and all in one the bed is starting to sag and meterial is pulling away from each other. we have had the bed for just over a month. the customer service consultant was EXTREMELY rude and unprofessional, she refuses to give me her surname as for me to report her, she refuses for me to speak to her manager and insulted me personally. i sent all the pictures of our bed through to the supp**** number as requested on my initial contact. now all of a sudden after the fourth phone call the STILL have not yet registered the problem or this has not been escalated to anyone. i am EXTREMELY disappointed in the services Aswell as quality of products. i have bought many of my household items through homechoice and have never had a problem up to now. I do not know what to do as I need assistance with this bed we bought as it is not just a cheap item that you buy every day. the ladies name was Siphokazi and the reference number is : ***
