Banned my account and will not give a proper explaination why.

This is the email exchange:
Me: I haven't used kongregate in a few years, and went to login now and appear to be banned for purchasing issues. This is news to me, as I am completely unaware of what caused this. My username is Sisco84. Any help on this would be appreciated. Thanks!

Them: Greetings! Having reviewed the account history, this account was banned for purchasing issues in 2016. I will not be able to reinstate access to this account.
Details behind this are available in the Kongregate User Agreement, which are linked below.

Me: Okay. That doesn't give me any information... If there was a purchase issue, why cannot I not rectify said issue? I'm unaware of any purchasing issues, and was never notified. I am getting a PC on Friday and wanted to play games as I haven't had a pc since 2016. How would someone get banned for "purchasing issues" in the first place? Suspend the account and notify the user? Is this legitimate or a joke that took me 3 years to find? I dont mean to be rude, but I'm seriously at a loss for words.

Them: Here's a bit of history for you:
This account was noted as having been tied to a credit card or PayPal purchase that may have been at risk. We reached out 3 times via email over the course of several weeks, banning the account temporarily twice in the process to attempt to force contact.
To protect your financial security, we banned the account and refunded any recent purchases at that time.
I hope that helps clarify the situation!
Thanks!

Me: I have never been told why... What exactly happened? I highly doubt that Kongregate cannot unban accounts they own... And I've literally never been told what happened... I've spent money on your website and never been told why I was banned outside of "billing issue"... What does that even mean?

On top of this, I never received any correspondence about having card issues. I wouldn't have thought to check them anyway, as there was literally no problems with my card. I made my purchases and moved on. The only reason they could have card issues is if they were trying to charge me after said purchases, which wouldnt make any sense. I have since went through my emails from them, and have nothing saying that at all. I do however have emails from them after my account was banned advertising video games. This doesnt make sense to me, and unfortunately, with such terrible customer service, I have no intention of spending money on their site again. Stay away, a "billing issue" resulted in all my progress being removed, and I did nothing wrong.
