Samsung Buy and Get Promotion such a ****!

In November last year, we purchased a Samsung Dishwasher because they were running the Buy&Get promotion 2017/2018. We thought that it would be good to do it that way as we needed to purchase airplane tickets (to visit family) and the promotion included flight tickets to the value of R4000. The dishwasher we had was still in good condition but we thought that if we do it that way we only end up paying R2000 for a new dishwasher (total value of R6000) because of the promotion. I made sure that I followed all the relevant steps required and completed the online submission by 5 January 2018 (deadline was only 21 January 2018).

I received an email stating the following: "Your online submission for Samsung Buy and Get has been received. Please allow for ten working days for your entry to be verified, after which you will be contacted via SMS. Please keep a copy of your reference number at hand 83AC85."

I allowed for the 10 working days for my entry to be verified and still did not receive my SMS. I contacted the buy&get team towards end of January where I could not get through to the consultants. During the beginning of February I had to go to Africa for work. Upon my return mid February 2018 I sent a follow up email requesting my SMS which i had not yet received. I did not receive any feedback. I sent another follow up email during March and still did not receive feedback. During beginning April a lady named Warda Stringer advised that "the campaign has closed and we are unable to honour your request". Reason given was that "Any online forms that have not been completed by 23h59 on 21 January 2018 will be null and void and the reward will be forfeited. " I responded stating that my online submission had been completed by 5 January 2018 and sent the proof thereof. I never heard anything back from the lady again. On 5 April 2018 I phoned the buy&get consultants and eventually got hold of a guy names Russel. Very nice and very helpful. He transferred me to the technical department to rectify the issue. They also didn't contact me back. On 23 April 2018 I phoned AGAIN and asked to speak to Russel. I advised him that I still have not been assisted with the issue and need clarification. He personally followed up with the technical team to try and assist. I then had to send all my follow up emails along with all the documentation i attached in my online submission. The technical team then responded with the following: "We regret to inform you that we are unable to assist as the Buy & Get 2017 promotion is now closed."

Can someone please explain to me how this works?!?!?!? I completed everything in time! I am so furious about this situation! I bought the dishwasher for this travel voucher, did everything on my side i needed to do within the deadlines, followed up constantly just to be told the competition is now closed and i forfeit my voucher. This is unacceptable!! I will never buy anything Samsung ever again and i will advise anyone not to because they just trick you into buying their products with promotions which cannot be claimed.
