SAMSUNG REWARD COMPETITION A JOKE

I bought a Samsung fridge on the Buy and reward competition hoping to use my reward in December . I chose uber lifts voucher. I sent my proof of purchase in November. Samsung said they would verify my purchase and get back to me in 1 0 days. I never heard anything from them until today when they informed me that I need to send another proof of purchase and that I only had until 25 January to do this otherwise I would lose my reward ! that sis tomorrow after they have bene sitting with my entry for over a month This is not within the stated terms and conditions of the promotion - they just see fit to make up rules as they go in order to cheat people out of what they call a win I hope this is not the standpoint of Samsung and just a mistake made by an uninformed worker who is not abreast of the consumer protection act and how it deals with competition redemption mishaps
