My partner has an Oppo R9. She loves it and I lust for it. The Oppo ‘ColorOS’ is Android with a layer atop that resembles an iPhone, but it obviously is not an iPhone and does not function like one.
Woolies might have done you over, but do not pass that blame onto Oppo as they are an innocent bystander as I see it. Their product is an Android phone that is intended to be comfortable for iPhone users via the ‘look and feel’. It has not been, to my knowledge, ever portrayed as an iPhone clone.
FWIW my next mobile will probably be an Oppo to replace my aging but still functional Moto G.
