Ignorant sales agents - Consumer Complaint for OK Furniture - Head Office

I bought a bed at OK furniture Midrand, everything went and I was told they will contact me when my bed is at the store since it was at the warehouse. After two days they called as promised and I went to collect. Upon my collection I signed for the collection and no sales person assisted me with my product as it was left outside. I had to figure out which bed is mine from the staff that was loaded outside. I took a bed as I was transporting it with my own transport. When I arrived home, I unpacked the bed only to find that the whole to put a wheel wasnt there. It looks like there was a wheel inserted before then broken inside and the bed was left like that packaged and sold, so practically I couldn't do anything other than to return the bed. When I returned to the store no one bothered to check my complaints until the sales person told me I could have checked the quality of the bed before I left the store of which it was impossible as the bed is covered with plastics. I demanded my refund yes I got it but please do something about your sales people and check your products cause to me it shows that you sell rejected products to clients.
