Roxie, I think sojo was speaking to the OP rather than you. It is clear from your posts that you are a professional evaluator. sojo is also a professional.
Much of the OP's post is not clear. She apparently turned in a receipt which had a time that did not match the time in her report. It sounds as though she did not explain the time difference in her report and the company disallowed her shop. She blames the MSC for this lack of payment and a number of other issues, including that she is unhappy that she chose to accept low-paying shops.
Sometimes pointing fingers and making it all someone else's fault makes people feel better.
