In December I purchased a Samsung 12000 btu airconditioning unit and received the buy&get special, I went through the whole process and filled in my free gift for the protea hotel in durban, my response was sent to Samsung on the 18-01-2016, two weeks later I contacted Samsung and asked what was happening and was advise someone would contact me soon, I've tried calling 3 times now but was no: 10 in line, can some just reply to my email sent or contact me on cell
