With Tekashi 6ix9ine being locked up, he is missing out on a lot of shows and money. However, these concert promoters are not trying to hear that at all. They want their money. According to TMZ, Tekashi was supposed to perform during Howard's Homecoming back in October, but he decided not to perform at that last minute. Instead, he performed in New Jersey the same night. You know good and well people aren't having that. Now some concert promoters have threatened to sue Tekashi if he doesn't pay back about $500k. The promotion company, Hits Before Fame & DMV Events believe that's how much they are owed, even though they paid Tekashi about $59k. They are adding ticket sales, marketing and other expenses. Word is Tekashi's team will handle the issues as soon as possible.
