Shocking service from Makro PE

On 02.02.2021 we ordered and paid for a ceiling fan, online. We also paid for delivery to a locker at the Engen Garage in Jeffreys Bay. On 06.02 I received an email to say that our order MAK*** had been dispatched. We have never been notified the courier that the fan has been delivered. We phoned the Makro call centre on 11.02 and then discovered that the courier had been given the incorrect cell number. Once again phoned the call centre on 15.02 to be told that the order had been dispatched. Still no confirmation by the courier. Phoned the call centre again on 22.02 and were assured that delivery had been made. Checked and were assured that the phone number had been corrected, which I doubt. Can anyone suggest what we do next? Makro’s service is unbelievably bad. The ladies at their call centre are polite but clearly have taken no action to ensure that the courier does have the correct phone number and apparently don’t know who the courier is. You would think by now our complaint would have been escalated to someone who is able to sort this out. At the end of this of this drama my Makro card is going to be cut into minute pieces and consigned to the ******* bin
