Takealot Return call has left sour taste Pick up call service sucks

Ordered an item, which I collected at the Takealot Richards Bay branch. It was a wrong item (incorrect colour) from the one I'd ordered. As per the companies return policy I returned the product, still sealed, to the Richards Bay Takealot pickup. Upon arrival they advised that I'd have to log a returns call against my order on my account, so that the correspondents at the warehouse in CPT could start with an investigation; which I did, a process which took half the day. At the end I decided to leave after waiting for an eminent answer that clearly wasn't gonna come soon. About 6 hours later the correspondents did email me, requesting photos of the product and barcode, for them to investigate further. I did this yesterday and have been awaiting the next step to getting what what ordered. Upon contacting the Takealot Richards Bay pickup, my calls have been repeatedly picked up and dropped this morning. I have in my position a wrong product and Takealot won't communicate with me to finish up the replacement process which honestly should be smoother than this. Ordered an item-wrobg colour delivered.
