Twitter Suspended my account without explaining the violation

Hello, my business account was suspended about a month ago and the reason I was provided with was 'violation of rules' without no further explanation on which of the rules have we violated. I submitted an appeal request but it was rejected with the same general 'violation of Twitter rules' as the reason and that further appeals and replies to the decision will be ignored.

I need to know what exactly have my company done in violation of your rules. This page was an authentic business page for a company registered in US and operating in 3 countries. We have registered trademarks in US and Europe and are serving 100000+ customers.

We have never published copyrighted content, we have never violated a trademark as we have our own trademark in multiple countries. so what is the reason? Is it logging in to account from multiple locations? is it about the content? Is it caused by the apps connected to our account like Crowdfire whose API was recently blocked by Twitter?

We have invested multiple thousand dollars in this account and collected about 5000 subscribers over years. and they suddenly kill the account without letting us know what we have done that violated your rules.

Does anyone know what should I do to to make them explain the violation occurred so I may be able to counteract?

Your help is much appreciated
