Numerous faulty products received and cancelations of orders without notification

We purchased a Go Pro hero 7 (white) for R3000. We were super excited as this was our first go pro and we were going to use this to video our new baby boys journey through life. All was well and Go Pro seemed to be working as intended until the first call to recharge, this was the start of a very unpleasant experience with the faulty products we received. After recharging the Gopro, the Go Pro refused to switch back on. We asked for a new Gopro which was delivered and this new Gopro seemed to be working fine until the found out the Gopro was not waterproof as advertised. We again asked for a new gopro, this time however they refunded the price we paid. 1. We waited a little while as the Gopro Hero 7 white was out of stock and the next available Gopro was R2500 MORE expensive even though its the same model but black. We finally manage to purchase another Gopro hero 7 with due date the 5th of Jan. Instead no phone call or notification was provided that the product won't be delivered, it was just refunded.

We

1. paid R3000 for a product we expect to work (being such a well recognized brand name). 2. The reviews were mixed but overall 4.5 stars indicating passed products were received by customers in a functional state and what was paid for. 3. We have spent thousands of Rands on takealot. This is the first time we experienced such terrible service and products. 4. Why are we expected to spend R2500 more a product rated worse on your app and why can't we get a working product that we paid for? Absolutely unacceptable
