facebook disabled

你係咪18以下?
如果係o既話, 你一定要o係60日之內加入一個中學network
唔係group/組別

如果係o既話, 你可以咁寫
Dear Sir/Madam,

My facebook account is disabled. I guess it is due to the fact that I didn't join any high school network. I will join my high school network if you can kindly enable my account again. Thank you very much.

Regards,
[YOUR NAME]

如果你唔知點解o既話, 可以咁寫
My facebook account is disabled. I am not sure of the reason. Would you please tell me about that. I will not commit the same mistake if you can kindly enable my account again. Thank you very much.
