Takealot drop the ball with return request

I normally rate Takealot 5 stars but not this time. A did a return request on 09/03/2018 which was approved and the items was picked up on 12/03/2018. The status of my request on 16/03/2018 is still "Scheduled for collection" after I inquired about is on 14/03/2018 and got a reply the same day that it will be investigated. I enjoy buying from Takealot and appreciate their return policy but they seem to be dropping the ball more and more with things like this.
