Don't worry man.You just go again to Ministry of labour,take a token of counter C,they will call you.Explain them about the problem.after that they will tell you to send an SMS to 92727.SMS format is 5.at the same time you will get a message from MOL and it says you can meet the committee on a date after one or two week.Go again that date before 12:00 and meet the committee .They will tell you what is the reason that they rejected your family visa.I am sure you will get it.Best of luck.
