False advertising or a ****

I purchased a samsung washing machine, dishwasher and fridge from a supplier. As part of the buy and get promotion I received 2 vouchers for my purchases of which I sent all the details needed through to them for their records and to recieve the 2 vouchers. I have been trying to process my 2 vouchers for the past 2 months to recieve the pin codes or voucher codes to use towards my flights and hotel. I either cant get through to the buy and get place when calling as it says no available agents at this time or I get through and the people I speak to have no clue what they are doing or are unwilling to help. This is making me think that the vouchers are a ********** way or false advertising to get people to purchase the samsung products but when it comes to redeeming the vouchers no one seems to want to help at all. Is this a **** Samsung????
