faulty lounge suite

last year in April I bought a lounge suite cash for my wife at Russels in promenade mitchells plain,I was quite excited about it because my wife was very happy, however in december my uncle came to visit ( a furniture inspector) and he was quite dissapponted in the lounge suite which made me very sad ,he pointed out all the faults on the couches which i never knew was wrong,I went back to the store in january this year (10/01/2015) to lay a complaint,the store manager (waghieda) told me she will log a call seen that the couches is still under guarantee,and on the 15th of january I recieved my first ref.no. They collected the couches on the monday and the store manager told me that it will be delivered on friday before 13h00 because the warehouse closes at 13h00,however they arrived at 18h00 the evening,after an inspection i found that nothing was done to the couches and the store manager told me because i was in a hurry that's why they couldn't finish it and that's after she told me that it will be done on the friday,however i went back and complained again,on 04/03/2015 they collected it again and since then im still waiting on my lounge suite to be repaired after 3 months.
