Failed to provide T&Cs

I purchased a Lenovo laptop on the 14/10/15 at CNA Vaal mall and feel Edcon should train their stuff on the terms of repairing their devices as I encountered problems with the laptop a day after I bought it and I was referred to Lenovo, which they claim they fixed. I had to deal with their supplier's (Lenovo) unfair terms and conditions on repairs which I feel I should've been told in order to make an informed decision when purchasing from CNA store. It is unprofessional and reflects badly on your stores as I have to use a laptop I am not sure will give me further problems because your policy says you don't have a return policy on this laptop. Which is unfair in terms of damaged products. Now I'm informed I can't insure it because I should have enrolled for insurance on the same as day I purchased which the consultant failed to tell me and now it is too late, I'm told.Your response in this matter is highly appreciated.
