Takealot - poor service with collecting parts!

I had a faulty monitor that slowly bur surely went blurry, and as it was less than 5 months old, logged a call with Takealot on 5th February 2021. All good, and got a good response to take it to the depot. I could only do so a week later, but boxed up the monitor and it was taken in on the 12th. Again, good response received about the monitor being handed in. I got notified that the VGA cable and power cord were not in, and I confirmed I had them. Takealot reached out to me saying a courier would be organised to come fetch it on the Wednesday 17th. Nobody arrived in spite of everyone being home. They asked on the 18th if it had been fetched, and I said no, and was then asked to confirm my address (they have that as they delivered it to me!). Subsequent to this, I was told again someone would fetch the monitor. And then 2 days later (Friday night the 18th) I got asked to confirm my address again. Since then, numerous requests about whether or not I need to return the cables to the depot, or if someone will fetch have gone completely unanswered. I lodged a query about this issue this morning (Friday 26th February) with no response. I have gone as far as asking them to credit me while the decide whether or not the cables are going back, and how (fetched or delivered by me). Honestly the worst service I have ever received! No responses are an exceptionally poor showing, and I hope this gets resolved.
