Hi Frog, calm down buddy, watch the blood pressure don't want a heart attack now.
1-Ok , firstly, if you take a contract were ever in this world, you get to see read your conditions before you say yes, so if you start complaining afterwards you really have to blaime yourself. If you didnt ask before hand for a copy of your conditions...then your were realy dumb.
2-Now if afterwards the company goes and moves the goalposts and changes the rules then you are entitled to moan and complain.

Now the remark "dont bite the hand that feeds you" can apply to no 1 but doesnt to no 2.
