I am afraid to say this is not an Intel® Official page. As you can see the email domain for their support contact is firstname.lastname@example.org which is not related to Intel®.
This seems to be a scam but as mentioned before, this is not Intel®.
I sent an inquiry at email@example.com and they replied that i can verify the promotion's authenticity by calling 0179.340.3000. I am not familiar with international phone numbers; is the above number the same with +44 1793 403000 number i found searching on Google for Intel Corporation (UK) Ltd. (a subsidiary of Intel Corporation)?
I am with Intel Customer Support and this is not an Intel resource. We do not know if this is a legitimate business and cannot comment about it. I will report it and will post back any finding but for now, I would recommend that you do more investigation on other Internet forums.
