Almost a month with NO REFUND..... HORRIBLE SERVICE

I bought an extractor at Makro on the 17th of December 2019, on the 20th of December i called to cancel the order and was told refund will be process within 10 days. On the 23rd of December 2019, i received an email stating that my order has been dispatched, i then rep**** and advised that the order shouldnt be delivered as i have cancelled it. Again, on the 3rd of January 2020 i received a call from the courier and they told me that my order is on its way, i also told the courier guy that the order has been cancelled. Yesterday i called Makro to follow up on my refund, the agent i spoke with told me that they are investigating and will give me feedback before end of day... its the 07th today and i still havent received any feedback. Marko must just close their online store the service is HORRIBLE
