Ironman bug, I don't know what to do

So, in sumary I did Ironman achievement 3 times already. None of the tries gave me credit for achievement. Firstly I tried contacting blizz with screenshot as a proof. Didn’t work. So I decided to record my last attempt. Apparently it’s not sufficient evidence, because it’s normal someone will forge whole 10min video (uncuted btw.) to get an achievement that gives 10 points.

i did report the bug after 1st fail attempt 1 month ago. Still doesn’t work, last attempt was yesterday.

Below links with ss with customer support and video of the last attempt:

(can’t post link, but they are the proof I want you guys to see)
Am I supposed to try 10 more times and hope it will work?

Hey there Dupacycki.

I understand that it’s frustrating to miss out on the achievement that you have clearly spent a lot of effort to achieve.

While I am sorry to say that we can not help provide you with the missing achievement here through the forums this is a problem that we are currently investigating further.

Thank you for letting us know and thank you for taking the time to provide detailed information. In the future please also make sure that you report it as a bug as you did.

The more information we can provide to our developers the easier it is for them to investigate potential issues and hopefully get them fixed.
