Buy and get promotion

So I reported SAMSUNG on the 30th of December here on hello Peter about the promotion they were doing which I did not get my voucher. To date the issue is not resolved, I got an automated sms last week that the issue is being dealt with and that an agent will call me. The guy called and just told me they are working on my problem. I mean why did the guy call it's now mid January and nothing is done. Samsung should really be careful small issues like this has big impact on them. I sure I am not the only customer complaining about this promotion. RESOLVE MY ISSUE ASAP. Iam tired of talking to your people with not result . I know after they read this complaint I am just going to get another reference number I don't want a reference number I need this resolved .***
