They wait until after i log off and then cut off my Direct Messages never while im on Twitter

I noticed on Twitter that someone cut off my direct message i turn it back on it was turn off again so i tweeted about it and said if it happens again i will take a pic and post it and i did after it was posted it was turned off again they don't want nobody contacing me about my truth i posted on there. Trolls dont know if its someone working at Twitter keeps turning it off i haven't broken any rules on they would have block my account.
