Takealot Dropping the Ball

I placed an order on the 9th of December with Takealot for a few Christmas presents. However today I received an email notifying me of a delay in the order and that I should expect delivery on the 30th of December. I contacted Takealot to rectify this matter where they cancelled the items causing the delay to expedite the other items and refund me the difference. What I find so disappointing is that Takealot takes no accountability and are quick to pass blame directly onto suppliers. I get that there are 3rd party sellers but I question whether there is any thorough vetting. Regardless, at the end of the day items are still sold under the Takealot brand and they should be working to rectify these problems internally instead of passing the buck.
