I bought a bed at Russell in kuilsriver on the 24th of November till today, they did no deliver my bed. Today they telling me that they are out of stock, and they telling me to take a bed that cost 2700, to replace a bed that was 3000 (normal price was 4500 before black Friday discount). And my bed was a queen bed, now they giving me a double bed. Russells and Joshua doore I want the same bed that I bought from you guys and please deliver my bed as promises, no stories.
