No holiday yet as promised by Promotion

Hi. I have bought a Samsung dishwasher early December and was told about this promotion. I have on the day of purchase registered to have a weekend away voucher. I have submitted my documents as requested and was advised that verification might take 7-14 working days. After asking for feedback almost every week, I don't get any and to date I don't have the voucher as promised by the promotion. This is not the service I expected from Samsung, deeply and utterly disgusted!!!
