This recruitment consultant is an idiot

I always can't wait to extend my weekend... but this weekend, I'm actually hoping for Monday to arrive sooner. BECAUSE I want to yell at someone! My recruitment consultant is a pain in my ass... I don't know what's wrong with this job agency (or probably just this person) because I always have had pleasant experience with them till recently. First, she told me I do not need timesheet because I'm being paid on a monthly basis. At the very last minute, I received an email dated nearly a week ago, asking me to fill them up and send it back to her. I'm not being paid overtime, paid hourly or absent on any days, even if I was, my company would promptly informed the agency, so what the hell am I filling it for? So I sent them an email asking them WHY, because I was told I don't need them! Next, comes the pay day, and they actually paid me nearly 40% less than what I am supposed to get for the month. I am almost fuming, I really wanted to ring her up and yell in her face. She should count herself lucky she hasn't given me her mobile number, else she wouldn't get herself a peaceful weekend. So beware on Monday!!!!!!!!!!
