Shocking service with one company blaming another - will it ever end

I purchased an item online, the item was to come with a free notebook as advertised. I have as yet not received the free notebook. After numerous calls to the customer call center I was eventually fobbed off to their supplier Fhirsttec was promised that the issue would be resolved almost a month and a half later still zero response despite having sent a couple of mails in between. I have been informed that I will receive a call from one of the Directors and yet I am still waiting - this is shocking service from both companies involved I am not interest in a call or excuses that it was an error on their part I want my free notebook.
