Worst customer service ever

I bought kids smart watch from Takealot and firstly I had to exchange 3 times because supplier provided alleged 2nd hand watch. There was a issue with watch all the time. Now last issue is that I ordered watch again with the previous returned watch refund. I was told that my delivery will be waived and my order will be delivered on time. Instead of that my order was cancelled due to outstanding delivery payment. It took 3 days again to get the reply from them and was advised to replace other order and replacement team will waive delivery fee and my order will be deliver on selected delivery day but none happened.

What a bad service and worst part that every time different agent email you back and you must explain the whole story but still not resolved. Worst service ever.
