Poor customer service and workmanship

i bought a very expensive leather couch from Coricraft Botswana and immediately noticed that the padding on the couch was not consistent throughout the entirety of the couch. Now after a few months of use some cushions have started sagging and the stuffing inside is pretty much dead. The couch makes terrible squeaks when you sit on it and sleeper leaves big folds after sitting on it much like a very old couch. I have not been offered any compensation in the form of a refund or an exchange, notwithstanding the fact that the couch is still under the first year of the warranty period. Only 2 inspections done which have not yielded any results.
