Did not receive the Bullets or Blades promo code!

I have the exact same problem as you. word for word. Here is a detailed account of what I have gone through thus far. This taken from email correspondence I currently have with Dell.

On 12/24/15 I decided to buy an alienware laptop from Dell's website. Part of this decision was based on the 3 promotions offered with the laptop. One of the promotions was Bullets or Blades GEforce GTX Bundle: Get Assassin's Creed Syndicate or Rainbow Six Siege. The second promotion was 10% rebate plus 2 day free shipping when you sign up for a Dell Advantage and Dell Preferred account. The third promotion was for a free Xbox controller. As of today, only the Xbox controller promotion has been honored.

Since the deal expired before it was promoted I did not receive it. I also didn't get an explanation or notice that I would not receive it.  On 1/8/16 I sent a Dell Support Request: Report a Missing, Wrong, or Damaged order/item. On 1/11/16 I received a reply back from SJ Bhavya that he would process a request for replacement of item #  800-BBKV. Bhavya stated in the email that I should expect to receive the item in the next 8 business days though the order status page said 1/27/16. On 1/26/16  I had not received the item and I reached out via instant messaging to Dell inquiring about it. By this time I had done a little research online and discovered that item # 800-BBKV is sent via email and not physically delivered.  I connected to L Kashyap via instant messaging and I explain the situation to her. First, she has to apologize for the long delay in her responses because she is instant messaging with multiple people. After a long period she finally tells me that I have to call Dell's customer service line and get help there. I call the number and I am connected to a woman that refused to give me her name. After telling her my situation, she tells me that I will receive my item tomorrow. I try to explain that it is delivered by email but she kept insisting that it will be delivered via package tomorrow. I tell her that I want to speak to a supervisor and she then simulates a transfer by staying silent then after a minute she gets back on pretending to be a supervisor. I tell her that I know what she is doing and I started repeating supervisor over and over again until she finally makes a real transfer(I know this because the on hold music played this time) to a man claiming to be the supervisor. I explain the entire situation again. The supervisor finally tells me that the offer expired and he offered me $75 credit in compensation. At this point I was livid with my horrendous customer service experience and demanded to talk to his supervisor. He then transfers me to the a random technical service person who transfers me to a dead line. At this point, I submit a complaint to the BBB. I am currently dealing with Sajith Narayananan from Dell. So far all he has offered is hollow apologies with no explanation and a coupon for $75 that requires an additional purchase.

The second promotion offered in my laptop purchase was the 10% rebate. The offer stipulated that I be a Dell Advantage member  and that I make the purchase with my Dell Preferred account(which I did). I signed up for Dell advantage then I made the purchase. This can be proven by the fact that I received free 2 day shipping which is included in the Dell Advantage rewards program. Though not originally included in my BBB complaint I did bring this up in a phone call with Sajith Narayanan who promised me that he would look into it. On the second call with Narayanan, he said there would be no rebate because I could not prove it.

As far as Dell is concerned the matter is closed but I am just getting started.
