A debt collector will not allow me to pay a debt, what steps should I take?
What you are describing here is the opposite of a problem: You're trying to contact a debt-collector to pay them money, but THEY'RE ignoring YOU and won't return your calls!  LOL!  All joking aside, having 'incidental' charges show up as negative marks on your credit history is an annoyance- thankfully you're not the first to deal with such problems, and there are processes in place to remedy the situation. Contact the credit bureau(s) on which the debt is listed, and file a petition to have it removed from your history.  If everything that you say here is true, then it should be relatively easy. Edit: See here for Equifax's dispute resolution process- it sounds like you've already completed the first two steps.
