When we opened it at home we noticed our speakers was damaged and our volume knob was missing.We notified them and placed our goods back into buy back on Saturday 22nd August with the understanding that our goods will be fixed.It's been 12 weeks, each week is a different story,first nothing at all was fixed and we were told it will be sent for repairs we should come for collection the next week,the next week they never even had a flippin clue as to where the system was ,hey could not find it in store and did not know if it was sent for repairs or not and my husband left the store once again without his music system, one of the managers Lee-ann then notified us it's been found and will only now be sent for repairs.My husband went today to collect it only to discover they've broken off some cable inside the amp ,meaning the radio won't work.
