Samsung Buy & Get Clain

I bought a Samsung fridge last year October and I was excited when I was informed that I could either get a holiday or a flight. I completed all the required online forms and took images of my Serial Number Image. I was contacted later on and was told that there was an error with my Serial Number Image and should retake picture and send it to [Email Removed] no later then the 25th of Jan. I comp**** and resent the Serial Number Image. I was not contacted by Samsung again, I tried calling the line but was told to send any queries to [Email Removed] I have send a number of emails but no response from Samsung. What can I do to get my promised holiday Samsung? Regards Tumelo Email - [Email Removed]
