Takealot nightmare

I bought an item a month ago, received an incorrect one upon delivery, logged a return only to receive the same incorrect item. I've had 3 agents assisting me on email but all three lefr me hanging. A pick up was scheduled without prior communication, but had to reschedule as I was at work. The line to reschedule was not working, called the call they rescheduled, drive gets to my house and finds no one but still logged the item as collected. All I've requested was for Takealot to confirm if they actually have the correct item in stock before I log a return, I wouldn't want to go thr9the return process only to get an incorrect item for the 3rd time. Why is it so difficult for takealot to just pick up the phone and fix this instead of having to wait days before written coree9is respondwd to?
