Samsung Buy and Get Promotion

In December I bought a fridge attached to a Buy and Get promotion, they gave me R6000 to buy something at their online store, I must say this to me were the reason for buying the fridge... When I went onto the online store the item I was looking for were not available to purchase, Samsung told me to wait stock is coming in the new year, so I did just that. When the stock finally arrived, I tried to use my voucher, at first it did not work, so I phoned and emailed Samsung, the promotions team did not even bother to come back to me, I phoned twice a day for the last week and a half to get a response and even demanded to speak to the manager in charge, I got the response he is in a meeting or not in the office, needless to say he did not try to phone me back. Eventually when I phoned again, one of the technicians pointed me to another site URL where my coupon worked, so it app**** the discount at last. Now I wanted to pay the difference, they accept credit and debit card, tried both and it kept on failing, phone Samsung again, then the told me hold on and try in a hours time, did this repeatedly with no luck. I phoned my back and they never received any online instruction from Samsung. Of course Samsung pointed out that the problem is with my bank... Wrote a mail again, the Samsung team gave me this answer :

Good day

Thank you for contacting Samsung Promotions. Kindly note that your query has been received and feedback will be communicated soon.

Kind regards, Samsung Promotions Team

So I did not get a response, this morning I tried to make payment again, the item was removed by Samsung from my cart, and now it say there is no stock of the item, they will let me know when it arrives. This is not fishy at all, all I can say is that I wish I did not buy this Samsung item on their buy and get promotion, I think it is false advertising and they do not have stock of the item I am looking for. This and their absolute poor service to customers is shocking, I am done phoning and emailing SAMSUNG, they are just ignoring their customers and the issues they create for themselves. Best steer clear of any of their promotions and false advertising.

I will not leave this issue and plan to take Samsung to the Consumer Goods and Services Ombud and suggest everyone fed up with their poor service and empty promises to do the same..
