Returns can be a pain!

I have been trying to return a portable aircon for 2 weeks now (it doesn't do much cooling). 2 ice block were missing in the return which they came to collect as well. All went well up to this point. Then 2 days later the aircon was redelivered. I contacted takealot to return the item and it was picked up a couple of days later (on Monday). Thursday another delivery driver pitched up to collect the ice blocks (which was already returned). I explained to them the situation and spoke to someone at the returns department and it sounded like they understood was going on. Today a delivery driver tried to deliver the ice blocks again, which I have refused to take delivery of.

Can you please sort out your returns department and get my refund sorted?
