Horrible service from click online store

Good Morning, I would like to just express my dissatisfaction with the clicks online store I purchased a juicer on the 26 November 2020. to do I have not received the juicer. instead, they have delivered the wrong product which is much more expensive. given the mistake made by clicks, they should prioritise this asap. but I am being sent from pillar to post with no sense of urgency.
