HELP with wall mounting kit for 27in iMac-late 2012 model

Can any one please help me... I brought 27in iMac in 2013. And I need to mount it on the wall.

To my amazement, I found out that I can not mount it on wall as my iMac is late 2012 model. And this model doesn't come with VESA wall opition.

when I brought my computer, I wasn't made aware of the opinion of wall mount or free standing stand.

I Have spoken with technical support but to no joy. I was told to replace my iMAC or buy 3rd party mounting Kit. Unfortunately the 3rd party kit will not solve my problem

I have wrote an email to Tim Cook, CEO, Jonathan I've, the Chief Designer but not heard from either of them.

I would be most grateful if someone out there can help me with my dilemm. Thank you hear from anyone soon .
