Recourse for what? Obviously, we have no information about exactly how the lender handled the accounting of your loan, and you didn't tell us whether the lender agreed in writing to the accommodations you mentioned. I'm also trying to figure out what you're trying to accomplish. If you want to make a payment and can't do it online, mail a check. And, if you intended to pay off the loan next month, then do it.
What did you think it meant "to put a couple of payments at the end of the loan"?
How could anyone here have any idea whether (and if so, to what extent) some unknown company might "work with" you? And no, that's not a request that you identify the company. The only way to find out if the company will accommodate you in any way is to call and ask.
