Takealot - Takealot is the grinch who ruined christmas

is The Grinch who ruined Christmas. And since they don't reply to emails or Facebook messages, perhaps naming and shaming on Facebook will help?
I paid for GUARANTEED delivery for 23 December. It was a Christmas Present for my 3 year old! Nobody contacted me from Takelot on 23 Dec, and it wasn't delivered. It is now 25 Dec and it is STILL NOT SHIPPED! I spent the day chasing Takelot yesterday from 9:00 when the call center open. Nobody ever gave me feedback, I sent repeated follow up emails that were never replied to. I had to keep phoning and reexplaining to different agents who kept promising I would get my delivery. It never arrived. So it's Christmas morning and my child didn't receive her gift. I had to rush around last night to make another plan!
I have sent a request to cancel my order and I expect a full refund. What is the point of paying extra to guarantee a delivery date YOU offered me?! This is shocking service ???
