Needs help about APEGA application

Hi folks:

I'm a newbie here and just want you guys opinion about my ordeal with APEGA ( Association of professional Engineer and geoscientist of Alberta. It happened that i applied for transfer of my EIT membership to P.Eng membership after acquiring the required 4 years of experience practising as an Engineer. (20 months an On-site Engineer in Oil battery and 28 months as a Process Engineer in Office. To my amazement, APEGA board member sent me a letter requesting additional 16 months of experience or I should apply for appeal. They failed to reference the factor they used to come into that conclusion.

My questions are

1) Has anybody here been in similar situation? What did you do? Please advice me
2) What are my changes if i appeal (According to the letter, I will have to pay for the appeal and would be bound by whatever new decision the executives make)
3) If i'm waiting to gain 16 months more years of experience, would i have to pay the processing fee again? would my application take another 1 year to process?
4) According to the letter i received, they only require an updated experience for the 16 months and a P.Eng reference, how would i go about this? would i apply online or send paper application?
5) any other helpful info would be appreciated.

Thanks
