Quick search on the forums with the "name of the retailer + cashback" will yield hundreds of threads with regards to cashback. As ever you need to be organised to benefit from them

Unfortunately rozeepozee mobileshop can barely pay their own customers so I think you won't get any joy out of them even if they have promised.
