Kitchen unit complain

Good day. I'm phylicia from Vosloorus.. Last year I decide to buy a kitchen unit and bedroom suit at Lewis store Chris hani mall. I bought this item on a credit account... Everything went well with the paper work, until the good were to be delivered at my premises.. There were only one person who installed the furnitures in my house, it happened there was some mistake with the kitchen unit. and the guy told me too go and report the matter. I went the following day and reported the case. The manager promised to make a follow up. I stopped making payment cause I saw my matter was never resolve. The unity became a disaster, am even embarrassed to tell my family n friend were I purchased this item. I even tried the head office.. And I didn't get any help.The only time they know when too call me is when they need their money. About the unit it seems they don't care... Am tired of this up and down.The manger promised to fix my unit till today am still waiting halve of the unit is on my spare room broken. She sended some random guy to fix it. This guy said he can't fix it cause he didn't install my unit..
