BuyandGet Frustration and no feedback

I purchased a Samsung Fridge from Hirsch where I specifically bought it because the salesman told me there is a Samsung Promotion. Submitted all my docs to Samsung on 30 December. They needed another picture of the serial number which I sent. I called the call centre again at end of January and the lady told me they are finalising the vouchers. Still no response. I then contacted the call centre on 9 February where the lady made me hold on for half an hour until she came back on and said they never received the email. I then resent the email to which she has agreed the email was received and the docs in order but have since heard nothing. I called again on 16/02/2016 an Josiah said that nothing has been finalised. I have been wanting to book a trip with this prize since December and now flights have gone up since waiting so long. This is misleading advertising as you make the customer beg for the prize which you guaranteed! Vuyaseka and Josiah both confirmed at the call centre that everything is fine but I still have not received my voucher!
