Very very poor customer service wastes my time.

Just one of the issues I have had with Takealot, there are many. Requested my invoice on the 10th of May, the day delivery was received, and 4 working days later, still receiving "copy/paste" responses to my calls and emails to Takealot, but no invoice. "The seller has 24-48 hours to respond." "We have reached out to the seller." Please be patient. NO! I have wasted so much time on the phone to their call centre, now I am going to start posting reviews on social media in the (vague) hopes of receiving my invoice eventually.
