I am trying to make a payment online and the only services they allow payment by is mailed checks, over telephone (for $12 fee), or by your checking account. I wanted to use my checking account so I put my routing number and my checking number in where it asked and it automatically recognized my bank. Now I went to the payment page and it asks for the amount I want to pay and my check numer. I don't have checks and I tried submitting it, leaving it blank and it said a number is required. I tried a 0 and that wouldn't work either. What do I do? I pay plenty of other bills with a direct account withdrawl...
