Takealot staff *****s returns and blames in on customer

I purchased a three-piece set from Takealot and collected it on the 10th of November. When assembling the items I discovered that the one arm rest was rusted. Called and asked if they could only replace the one chair and was told because it was a set I needed to return all the items. I then took everything apart placed it in the original packaging sealed it up and return it to the Brackenfell pick up point on the 11th of November. I received an email on the 13th of November from Takealot telling me that there are parts missing that i need to return. Went back and forth via email and called in telling them that everything was in the sealed box, and I can explain to them all the parts. It went on for three weeks and I saw on my app that the return was concluded, and the return was rejected. I called again and demanded to speak to the a supervisor on the 26th November. He then explained he will sort this out on his side. The status on my app changed to product approved for return but i have heard nothing frrom Takealot or change in status. So i basically paid R1000 for table and chairs Takealot staff stole.
