Buy and get sweet nothing - thanks Samsung!

I recently qualified for a free return flight when I purchased a Samsung appliance. After going through the rigma roll of registering my purchase with Samsung, I was told to simply call a number to redeem the deal. In short, I eventually got through to the very busy call centre on 27 Jan 2016 and to my surprise had to complete additional steps to book a flight. I sent in the required info on 28 Jan 2016, but didn't receive any communication from Buyandget. I followed up by email and still no response. I then called the call centre again and was informed that Buyandget was unable to stick to a 48h turnaround time as they were receiving high volumes of claims. Buyandget eventually contacted me telephonically to confirm details regarding my request on 1 Feb 2016 and assured me that she would contact me by 3 Feb 2016 to finalise my booking. Buyandget gives no contact number, so I am unable to follow up with the consultant. I sent a complaint to them in writing, but they have again failed to contact me. Buyandget is either ill-equipped to attend to its customers or completely disinterested. I am now left to book my own flight because Buyandget is unreliable. Thanks for nothing Samsung!
