Energy Engineering recommendation letters and IT course

I am going to study Computer Science at Master Degree level, but I already have recommendations, which are pretty much connected with my Bachelor Degree (Energy Engineering), there are some thoughts about my attitude, participation in previous studies, but not directly about IT skills (and unfortunately at the end there is mention which studies I am able to participate in as a Master Degree student). I can't change it, because they are already signed. I'm not gonna apply to the best unis, but that will be my drawback and maybe I shouldnt send it? But if I shouldnt send it to the uni office, I dont have any other recommendation letters. I got a plan first to finish MA in Computing and 2-3 years later come back to my BA faculty and study MA in Sustainable Energy or Mechanical Enginnering. If you ask me why I am not continuing BA, there are currently no jobs in this area in my country. I'm just gonna wait and think which branch of engineering will develop the most (but I will try to keep in touch with energy/mechanical area).
