What is going on with the management and staff at Takealot

I have purchased from Takealot for many years without incident. Returns were refunded or credited and orders were timeous. Since the Covid19 lockdown went into effect it’s as if the processes at Takealot suddenly went for a loop. I've returned a faulty keyboard and mouse approximately the end of May 2020 and to date after also sending back the batteries as well, as of about 10 days ago, they are still reviewing my return. My returned items were in a brand-new condition and that's what’s strange since they are also well within the warranty period. My initial attempt to contact Takealot telephonically about the returned items resulted in a voice message redirecting me to mail them. I did that at least 4 times since and no one has called me back to explain the delays. It's beyond me how this is even happening. Who is guiding this ship? Added to this I ordered 2 more keyboards since to replace the returned one. Either time the item was available upon the order being placed yet a week later I was informed they were no longer available. This had a direct impact one me successfully working from home. The delays experienced in 2 more orders for different items has been frustrating lasting more than 2 weeks. 2 more items were suddenly not available and taken off those orders. Another issue was one of my items got missing upon delivery and the courier was unable to find it. I logged a call to Takealot. It was eventually sorted 2 weeks later. No one called me to discuss what had happened or apologised for the mishap. This may sound like a customer moaning but look at the above and when you see this all happened within the last 5 weeks it becomes clear something is not right at this business. In fact this is unacceptable service.
