UPS-Hikvison-product advertising misleading

Bought a UPS..Hikvision online...requested a return the next day as it only lasted 90 mins...was not going to benefit me as I am working from home and am using a laptop.Got a called from someone at Makro and I explained that the reason for my return.I then received an email stating that the return was rejected as the item was tested and found not be be faulty and that it was not in its orginal package.I have a video of the item been packed by me.It was in it's orginal package.Makro has not contacted me since then.They are selling on behalf of vendors,hence they need to take responsibility for returns if the item is not as described.This type of service will definitely stain Makro reputation and consumers will refrain by purchasing online.My next recourse would be my bank to confirm if I have a dispute right as well as making contact with the ombudsman.
