Inferior Dell Laptop

I purchased a Dell 7348 I5 Laptop on the 07/05/15 form Incredible Baywest Port Elizabeth.I must clarify that My laptop was always in a proper laptop bag or on an office desk.With all the laptops I have had ( I upgrade every year) ..This is a first one I see that the case started fading and turning colour around most of the edges. Seems burnt. I have done some goggle searches to check if anyone else has a similar problem, to find their are numerous complaints about the exact same model ..case fading and turning colour.(Burnt like look).returned to Incredible Baywest Port Elizabeth on the 09-10-15 at No date ,no Time written on return slip! manager was not interested in coming to speak to me or even looked at the item. Lady at the counter was unable to give any indication as to how this will be handled! All she said was ! It would take 3 to 4 weeks before we will get assisted due to the supplier been overseas e.t.c which has no bearing on me! I did not purchase from the supplier. I want a refund and not a replacement! Incredible is doggie company to deal with.
