Terrible customer service

<p>I had purchased a washing machine during the month of May 2016. I was given a leaflet with the promotional details on it and was advised to contact Samsung to redeem the offer. I had contacted Samsung to redeem and was told to get the voucher from the Samsung store, thereafter i was told to contact Unilever to get the vouchers. I had contacted unilever on the contact numbers given to me, and there is just a voicemail message stating that the person will be back on the 20th. What is the point of offering a promotion and stating how to get the offer, but when i try to, no one can assist?</p>
