Incorrect order delivered-no refund or exchange

My order was placed 2 months ago. I received my delivery on 27 Sept to which the contents was incorrect. I called bottleshop on ********** 104 and emailed them on ********** asking for a return collection to be done. It's been 2 weeks and I still have the incorrect order with me. Bottleshop refuse to provide a collection reference and refuse to respond to my calls and emails.
