Disappointed about the services provided by russells

I've made a purchase at a Russell store in Durban. I've bought both a lounge sofa set and a dining table set. My initial suggestion to the store manager was that I would pick up my own furniture but upon policies in regards to damages I was told that it's best if the store makes the delivery. On Monday I had received my lounge set but the dinning table chair was defective it was a whole process in order to get an exchange of that table but the store manager agreed to a return. Today being Tuesday I've received another dining table set but that order was defective as well! And I was promised another set this afternoon which they failed to provide!How is Russell's furniture even a reputable company when they provide such inefficient and unprofessional service? As per the customer protection act of South Africa I am entitled a return because the fault is from russells warehouse not ours. I've spent two days at home from work trying to sort this matter and countless of hours on the phone trying to resolve this matter.

Some assistance will be greatly appreciated.
