Dell financial services is serviced by webbank. I am not 100% sure but I think they have an arbitration provision in the contract, one of the forums is JAMS and just the initial bill to the business would be thousands of dollars. A full blown arbitration will likely surpass $10000 but I think you are only responsible for $250 of the arbitration costs. You might be able to get some leverage this way. Even if they do pay the initial bill, I wonder how they will justify over $3000 in charges from a $750 purchase. If you decide to go this route, you need to read the contract carefully and research your options. Good luck!
