Do you have formal written agreement for your plan? If so, you have a contract that they must comply with.
If not, then you dont have clear evidence of agreement until they accept a payment.
You have, in my opinion, a hanging issue as to whether you have a valid payment plan agreement. Yes, I would contact them and inquire as to whether or not they have accepted your agreement. Until then, you are left hanging....
