Bad customer service

I placed an order with takealot and have done so many many times over the last number of years. The order was delivered on the 25th May 2020. I accepted the order and placed the box in my garage. I didn't open it for a few days but when I did, I noticed several items I ordered were not in the box. I queried this on the app and long story short there has been a lot of back and forth emails but as of today this has still not been addressed by takealot. I even had to send CCTV footage to you! You are still sitting my my payment but have not fulfilled on the order. This is grossly unfair and this type of customer service is shocking. I have ordered many many times from your platform before but this lack of customer service just leaves a sour taste and will make me think about ordering from other sites as a preference. Would appreciate if this could get escalated and sorted out.
