Relocation Expenses

So on the glorious day when I got hired by the circus, I was informed that they would be paying for all of my relocation expenses. This included movers, per diem meal money, mileage, etc. At first I was very excited about the seemingly hospitable treatment but the true colors of the shitshow were soon to emerge. After I moved to my new city for my new shitshow job, I took all of my receipts and expenses (on the first day of the job) to the appropriate people at the shitshow to approve my expenses and pay off the balance on my corporate credit card. Six months later, I received a statement in the mail saying the balance was never paid and I had monthly late penalties and interest. So the NEW bill was the original balance of my expense reports PLUS the interest and late fees. This is where things get interesting. The original amount expensed was now not enough to cover the new bill. So I go to the appropriate people to file another expense report and, strangely enough, I noticed this seems to be a common occurrence. So another 4-5 months go by and the payment goes through to my corporate credit card but there is still an outstanding balance of the late fees and interest. So I file another report and 5 months later, it actually gets paid while more interest and late fees accrue. This process keeps going on for about 2 years before I finally get a balance of $0. Because of annoying experiences like these, I throw rocks.
