Makro Online incompetance

On the 29/01/2018 I ordered a Thermometer online from Makro. Delivery showed 2-5 working days. After several phone calls to Makro still not having received the item I canceled this order on the 23/02/2018. Refund details showed 2-5 business days, today is the 19/03/2018 and I still haven't received the item or my refund. This is unacceptable and completely unprofessional. For such a large retailer one would think that they can either deliver the item or pay me my money back.
