damaged couches

in 2013 may i bought couches at Geen & Richards Westgate mall , after 2 months i discovered they were defected and went back to the store to raise the issue to the manager . i was told to email pictures of the damaged couches which i did , then i was sen from pillar to post as to who is responsible to assist me . when they closed down African Bank took over and i raised the same issue , there i dealt with different people and was told to go look for the supplier who manufactured the couches and get a quote from them as to how much to fix them and only then they could help . when i couldn't track the supplier ( Italian company ) i was told to get anyone who could fix them of which i asked if it wouldnt compromise the quality and got told that was the only way they could help . again i was sent from pillar to post people handling my case resigned ( apparently ) until the warranty expired , now they call me at 6 am telling me to pay and if i do not pick up they will call through the day , i wish they were this passionate when i needed help
