PAYMENT PLAN SERVICE DISASTER!!!

I have been calling the whole to make a payment arrangement with this company to settle my ovedue amount with them but no one could give me the proper channels of doing this. Not even a specific person or department was given. After numerous phone calls and diffrent telephone numbers being given to me (none working - keeps disconnecting) I am so livid right now. If they don't want me to settle my account, they must just say so and clear my name at transunion. I mean really, is it too much to ask for...
