Have I been refused access?

I have searched the forum as best I could and couldn't find an answer for this one so I am posting this question...
I applied for a TN a month ago and was refused due to lack of paperwork. I was allowed to withdraw my request with explanation on how to fix it. I applied again 2 days later with the "problems" fixed but the new POE officer had other issues with it and refuse to make sense of some of the definition he thought were a loop hole to get through so it was refused again.
I abandoned my quest for TN after this.
I drove to Winnipeg (from the Sweetgrass border) and entered the US for a visit at the Pembina border. Of course, this raised all kinds of questions and got me accused of attempting fraud and threatened with jail and $50 000 fine, accused of forging documents, working illegally for an American company already (none of which was true, I am clean there) so to make a long story short, after a gruesome 5 hours interview "Hollywood style" I was allowed in under a B2 visa for a preset amount of time (10 days. I came back after 7).
My question is this.. seeing as my TN have been refused on the ground of lack of proper documentation, when asked "Have you ever been refused access to the US or have you ever been escorted out?"...what should I answer? I go often to visit friend. I don't care to work there anymore at all.

Anyone else been in such situation?

The answer is yes, you hve been denied entry, and answering anything else would be lying; it is now on your dossier, and you should expect added scrutiny each time you cross in the near and middle future.

But, you were allowed in, which, despite all the bluster and interogation, means that they had nothing on you. Your 'mistake" was to try and re-enter so soon after a denial, at a different port.

As long as you subsequently left and gave in your I-94 to the Cdn authorities before the expiry date, you are fine for now.

But, each time you enter form now on, have clear documented plans, and clear evidence of a likelihood of returning to Canada (like a job), and no evidence that you are doing or wishing to do anything but visiting, shopping, etc (no resumes, no TN documents, etc) and do not even think about lying as to your intentions.
