Bad service

I had made a purchase online on the 22/09/2017 for a health griller which was on a sale. A week passed without any communication from clicks about my order until I followed up on their promise to deliver within 1-3 days. I was told the item is out on delivery of which the lady spoken to couldn't even identify nor tell if the item was in stock or not . I was phoned back by Carl who promised to fast track my order and I even gave him my clear and right physical address as he alleged that my address on the system was incorrect. I even offered him my mobile number in case the courier people experience challenges. I made a follow up again today (12.10.2017) and the agent gave me contact details for the courier guys and they indicated that the tracking number on the system on my purchase order history by clicks is incorrect. its been a while now and no one seems to be bothered by query hence I am the one who is always at their back instead of them keeping me abreast of any challenges . This so low, poor of customer service , disrespectful for customers and inconsiderate of clicks to do this. I am greatly disappointed by this and feel like my rights as a customer have been violated.
