VERY bad service.

I buy a lot from Takealot for our business. Order nr ***. Never had I had such bad service. My order should have arrived on Thursday, 7 November. Nothing came. I've e-mailed Friday morning, enquiring about the order's delivery time. I got no answer. I emailed again on Monday, 11 November, no reply on the email, just an sms saying that they tried to deliver, but couldn't - why not - I was sitting in my office, this was just after 9 yesterday morning. I've emailed again asking about this - no answer. I emailed again this morning - no answer, only to receive another sms 13:14 to say they tried to deliver but could not - why? Again I'm sitting in my office. I've emailed again, but still no answer to my emails!! - O and you cannot even phone Takealot.....
