Bad service for their human error

They sold me and my sister couch without all the legs and now it is broken in the middle, I reported the incident they are attended the matter after 10 days, came took the couch and said they are going to access it and let me know if it was negligence or not after 7 days I went back to the shop in Kollonade Dipuo said they were off line and I should leave my numbers they will get back to me and I should have just call rather than coming and she never phoned back on the 11th day I tried calling but their contact was not working, but I had Abel ' s cell number and I checked with him and he was surprised that they have not returned the couch , he contacted them the warehouse and they brought it back with no legs still and the couch is not straight after repair I am not happy with it, it was not my fault that they gave me a couch without complete legs and because it was not balanced it broke now I have to be with a couch that is broken and skew in the house. I am not happy at all and it will break again because what caused it to break isn't fixed, they should just came and take their couch and gave me my money back or give me a couch that is fine and stop giving me excuses, they did not give it to me for free I bought it with hard earned money to be comfortable and not to stress about the stupid couch for the error that wasn't my fault.
