We ( my son & I - as co-signer ) have XXXX loans w/ Sallie Mae XXXX 
Last month - they took the XXXX payments sent ( XXXX check for each loan ) and applied them both to the same loan. In their system - this triggered a 'Late Payment ' on the XXXX loan that received 'no payment ' and started an incessant series of phone calls to both my son & I. 

Their error was pointed out to them within a week and - despite the promise of the error being corrected on their end.. the phone calls kept coming ( XXXX - XXXX calls per day.. to both of us! ) Two weeks later.. we were still getting the calls and the payment error ( that THEY made ) had still not been corrected. 

I call again ( I 've now been on the phone with these people for over an hour ) and I finally get an assurance that the error will be will fixed within 24 hours ~and~ that the calls will stop. 
The error is fixed ( although it takes 3 days to do so ) - but the calls continue until their system shows the payment corrected. 

Now - just a week after THAT issue is cleared - I just found out that they did the same thing to the most recent payment ( s ) ~and~ I was charged a 'late fee ' on the account that THEY screwed up last month! 

I am now faced with, yet another, unending series of calls and - as I told them during the last phone call.. I consider these calls to be Harassment! 
Aside from filing a complaint with ConsumerFinance.gov - do I have any legal recourse against them?
