Terrible customer service

I ordered a waist trainer in Dec 2025 but accidentally selected the incorrect product upon delivery I realised my mistake and immediately contacted Takealot to rectify issue. I’ve made numerous calls and have been speaking to different agents who seem to understand my request and then they do nothing about it. I spoke to Linda M in Jan who requested that we send her an email which was done and then again nothing happened. This morning I spoke to another gentleman I just forgot his name. I need the incorrect product to be collected from my property, and then credited so I can re-order the correct item!!! That cannot be this hard to do!!!!! Can someone please assist
