Unfair customer service and lack of communication

I bought couches in July the 20th,a week later the steches were coming out and I went back to the store to report an incident they came to collect the couches. Two weeks later I went back to the store to enquire and I was told they are busy looking into my matter and tgat I will have my couches back till date I don't have couches, sad part is that I'm working from home and is difficult to do work sitting on a bed the whole day and that resulting in ne having back pains which I ended up in hospital, I went to to the doctor 3 times and they reffered me to hospital, Akhona funisher will have to pay for my medical bills and refund my money back as this kind of service sucks and they don't want to acknowledge or take accountability for their actions they still have same couches in the store and I don't understand why can't they exchange it.
