Horrible after sales experience!!

I purchased a Packard bell laptop form them and when I received and opened my order I realized it not something I want as it won't be compatible with my studies. I logged a return request for them to collect and cancel my order. It's been over a week that I'm given a run around for photos of the laptop as they say they can only collect then after!! I've sent numerous photos and they keep wanting more and more!! How will I take a photo of the laptop in It's sealed original packaging when It was opened?? How was I supposed to know what's inside if i didn't open it? Now they also want an o screen where my image is not showing!! Making this order was the worst mistake I've ever made!! The laptop is going to them..why don't they assess it upon arrival then giving me all this never ending stories!!?? They don't even bother to call and explain or enquire about my request Gugulethu just keep sending endless emails!! If you want to maintain your peace DON'T order from them!!
