Not receiving any feedback with my voucher sms

I bought a Samsung 6kg washing machine last year and registered on the BuynGet site with all the required info before 31 December 2015. At the end of the registration it showed that it will take up to 7 working days for me to receive the sms with the voucher code on. Until today I am still waiting for that sms. I've contacted Samsung and asked for the BuynGet contact details. I then emailed buynget, no feedback received. I contacted Samsung again and got a contact number. Called them and they said their system is slow but i will still receive my code in the next couple days. 2 weeks later and still no code received. I called them again now, but they are not taking calls anymore. So I emailed them again. Still no feedback received. I don't understand why it's so hard to get the things you were promised when buying their products. <br> <br> Please can someone get back to me about this as soon as possible, I've been too patient for too long!
