SA's favourite toy store - You must be joking!

Long story short, I ordered Lego during the 3 for 2 special at the end of June, opened the box and there were only 2 sets, the most expensive one being absent. Sent a query on 31 July, ticket number 3012. Receive an automated response, high volumes, please be patient, blah blah, we hope to make so smile within 48 hours. No further reaction. Send another enquiry on 6 August, to find out what happened to the first enquiry, same automated response, no further communication. Receive an email from them on 11 August, asking me to rate their service (???!!!! what service?), respond that I'm unhappy, no response. Tried to access the link provided in that email again this morning, message pops up that this enquiry has now been closed. My son's birthday has come and gone, I'm still out of a Lego set and apparently customer service is non-existent. There is no branch in the small town where we live. What the heck next? Use Takealot or Toysrus, I've never had an issue with either. First time using Toy Kingdom and it was an utter disaster.
