Poor service from Telkom upgrades

I upgraded telephonically and ordered the Samsung galaxy A31 and then I received the Samsung A30 on the 30 July. I then called telkom to inform them about this error and was told by an agent that they would send an email to their team leader and they would get back to me within 48hours but i never received any response.I even sent a message via Facebook messenger to Telkom to inform them about the error and only received a message on messenger on the 6th from Maggie who asked for my address so she can forward the details that they can arrange for the device to be picked up. I didn't receive any feedback from Telkom and i kept calling and was told that they are sending a message to their team leaders and the agents cannot do anything as they are working from home.One agent even said i must go to a Telkom shop but when i did go to the Telkom shop in Waterfall Mall i was told that they cannot assist me as it was a telephonic order so i must phone 10213. Am not happy with Telkom's inability to handle my query and i even want to cancel.
