Quick to take your money slow to fix their mistake

I ordered an item online through the Takealot app. Took about a week before being told it is a the drop off poi t. Went to the drop off point and picked up the parcel. Immediately I noticed the dimensions were wrong. I opened the parcel and it confirmed my fears... It was a wrong item. I immediately told the staff at the pick up point that I want it returned. They had power issues and I did the necessary on the app for it to be exchanged/returned. After the staff had gotten the power to their system back on they couldn't accept my packet. On my it showed a case was opened with reference NR. And their system couldnt find the reference Nr. 24 hours later and the parcel is still in limbo. The status is " checking eligibility" and Takealot cannot take the package officially back as the status is a problem Funny to buy the item and pay for it took less than a minute. Too have Takealot fix their problem of delivering the wrong item more than a day and counting...
