Ubisoft I got banned for cheating when I did not cheat San Francisco California

I was banned by their anticheat software, but I was not cheating. I have no history of cheating on any of my games. I have no cheating software installed on my computer. I did not cheat in this particular game either. I asked the support to at least provide evidence that I had cheated and they responded by saying they had evidence, but they wouldn't reveal it to me. I asked for a list of program(s) that I was banned for or gameplay footage of me cheating and they couldn't even provide me with that. I paid 15 dollars for this game and even put an extra 5 in for digital content and I couldn't even be given evidence as to why they revoked my privilege other than "we have proof."
