Poor Customer service

After being given a run around with getting my refumd from vodacom, i decide to try and purchase a phone with them again online. I purchased the phone on the 14 April 2023 and it was supposed to get delivered on the 18th of April 2023 by their courier RAM but it wasn't delivered, i did a follow up the courier company and they said Vodacom did not provide them my delivery address ans contact. When i gave they said they've lodged an query with Vodacom. The delivery is 2 days late i've been told by the delivery company to contact Vodacom, i've been trying from my side and i have no response. This is my second issue with them in a space of 2 months
