Agencies are like leeches

I was called upon today to sign my contract with an agency for a position in Saudi. I told them that I don't like the package that they are offering. I want them to review my demands and give another offer. Then suddenly out of the blue she told me that I will be going with 4 other engineer, so you can share a flat with them. Then I said "WTF!!!" I don't care about the others, I am negotiating for my own salary package. I was so pissed off that I told them that you don't have the right to reason with me, that's my demand, if you can't give it then I won't take it. Probably they were so devastated that they won't get a penny from me unless I sign the contract. Well booooo hoooooo!!!!
