First off, you didn't get 1.2BTC with $80AU, you got 0.0012 (or 1.2 mBTC)
Secondly, the transfer from the exchange to Electrum cost you 0.0005BTC, why would you blame that on the Electrum wallet and not the exchange?
Thirdly, sending the BTC back to the exchange then cost you 0.0002BTC as Electrum calculated the fees at this point (note how Electrum's fees were lower than your exchange fees)
Fourthly, BTC fees are high currently.
It sounds you like you need to educate yourself a lot more before you accuse anyone/thing of being a scam. I can't believe you had the gall to find this bitcoin forum, create a username like you did and then look as uneducated as you have.
